2026 CHAU-SHI Series – Din Yue Open

Round 4

July 4, 2026

The final round of the 2026 CHAU-SHI Series – Din Yue Open, offering a total purse of NT$5 million, was played today (July 4) at Taichung International Golf Club. The championship battle remained intense until the very last hole, with four players from Taiwan and Japan contending for the title throughout the final round.

Taiwan's Chang Shih-chang birdied the final hole to claim victory by a single stroke, capturing his first title in nearly three years and earning the winner's prize of NT$1 million. He carded a final-round 69 to finish at 19-under-par 269 for the tournament.

Defending champion Wang Wei-hsuan and Japan's Shori Ishizuka each shot 70, finishing tied for second at 18-under-par 270, one stroke behind the champion. They each received NT$335,000 in prize money.

This marked Chang Shih-chang's first victory since winning the Royal Open on the CHAU-SHI Series on July 14, 2023, ending a nearly three-year title drought. He expressed his gratitude to all of his sponsors, including Yeangder Group, Taiwan Glass Group, Tai Fung Golf Club, Hsin Feng Golf Club, Step Golf, Jhu Feng Construction, and Chang Yao Construction.

Japan's Rinkei Shinzato, who still held a one-shot lead over Chang after 17 holes, suffered a dramatic collapse on the final hole. He four-putted the 18th green, recording a double bogey. Despite shooting 69 for the day, he finished alone in fourth place at 17-under-par 271, two shots behind the winner.

Lee Chieh-po fired a 68 to finish fifth alone at 272.

Lee Jui-shen shot 68, while Chan Chia-han posted 70. Both players finished tied for sixth at 273.

National Golf Country Club amateur Ko Liang-yu produced an excellent final-round 65, finishing with a four-round total of 282 to win the Low Amateur title. He also tied for 36th in the overall professional standings.

The tournament was title-sponsored by Din Yue Co., Ltd., organized by the Chinese Taipei Professional Golfers' Association (TPGA), and co-organized by Taichung International Golf Club.

Chang Shih-chang began the final round in the last group alongside Wang Wei-hsuan and Shori Ishizuka, with all three players tied at 16-under-par 200 after 54 holes. Through the front nine, Chang recorded one birdie and one bogey, leaving him two strokes behind Rinkei Shinzato, who had moved into the lead, and one shot behind both Ishizuka and Wang.

Chang said he stayed patient throughout the front nine. Although he had recently switched to a completely new set of irons and felt they were performing well, he struggled to adjust to the slower greens, which had been softened after the rain, resulting in several missed putting opportunities.

After making birdies on the par-4 10th and the par-5 13th, Chang caught up with the other three contenders, leaving all four players tied at 18-under-par.

The first pivotal moment came at the par-3 16th. From 185 yards, Chang's tee shot missed the green to the right and settled in the rough. Faced with a difficult short-sided recovery, he chipped to within four feet and calmly holed the putt to save par.

The decisive moment came at the 18th hole.

By then, Shinzato, who had already completed his round in the group ahead, had fallen from a one-shot lead over Chang to one stroke behind after making a double bogey on the final hole. Meanwhile, Wang Wei-hsuan and Shori Ishizuka were also one shot behind Chang as the final group arrived at the closing hole.

Although Chang's drive drifted into the right rough, he safely punched his second shot back into the fairway with a 9-iron, leaving himself 108 yards to the flag. His crucial third shot, played with a 52-degree wedge, landed beautifully on the green and stopped just three feet from the hole. Chang calmly holed the birdie putt.

Both Wang and Ishizuka also birdied the final hole, but Chang's birdie was enough to secure the championship by a single stroke.

Chang said it had been quite some time since his last victory, and standing on the championship podium again even felt somewhat unfamiliar. Over the past two years, he admitted that he had been under considerable mental pressure. Fortunately, the birth of his beloved daughter helped shift his focus in life and allowed him to approach golf with a much more relaxed mindset.

He also revealed that a shoulder injury suffered earlier this year had caused his performances to fluctuate. Even so, he insisted on continuing to compete as much as possible to maintain his competitive rhythm. Now that his shoulder has recovered to about 80–90 percent, he was delighted to return to the winner's circle and hopes to be fully healthy in time to perform well in the upcoming Asian Development Tour (ADT) events to be held in Taiwan.

Defending champion Wang Wei-hsuan carded six birdies and four bogeys in the final round. After the round, he said his overall performance was actually quite satisfactory. However, the rain the previous night had slowed the greens considerably, making it difficult for him to adjust. He missed several short putts and was occasionally inconsistent with his iron play. Although he was disappointed that he could not successfully defend his title, he said he had given his best effort and believed that enjoying the game was the most important thing.

Japan's Rinkei Shinzato, who eventually finished fourth, said afterward that he was extremely disappointed. Feeling overly nervous on the final hole, the par-5 18th, he four-putted and made a costly double bogey.

His third shot reached the back edge of the green, leaving him with a downhill putt of approximately 33 feet. His first putt came up short, leaving about 13 feet remaining. He then struck his second putt too firmly, watching it slide three feet past the hole. His third putt also narrowly missed from three feet, and he finally holed his fourth putt for a seven on the hole.

Starting the day two strokes behind the leaders, Shinzato charged into contention with four birdies on the front nine to reach 18-under-par, taking a one-shot lead. He extended that advantage with another birdie on the 17th hole, remaining one stroke ahead of Chang Shih-chang, only to suffer a heartbreaking collapse on the final hole.

The tournament was held from July 1–4 at Taichung International Golf Club over 72 holes. This marked the second consecutive year that Din Yue has served as the title sponsor of a TPGA Tour event after upgrading from sponsoring a Challenge Tour tournament last year. It also marked the first time the total purse was increased from NT$3 million to NT$5 million, while the champion's prize doubled from NT$500,000 to NT$1 million, significantly enhancing the tournament's competitiveness.

In 2023, Din Yue partnered with Ju De Environmental Protection Co., Ltd. to title sponsor the Din Yue Ju De Challenge. The following year, Din Yue independently title-sponsored the Din Yue Challenge, with both Challenge Tour events offering total prize money of NT$1 million. To provide Taiwanese golfers with a higher-level competitive platform, Din Yue upgraded its support to a TPGA Tour title sponsorship last year. This year, the company not only continued its commitment but also substantially increased the tournament purse.

This tournament is the sixth event of the 2025 TPGA Tour and the fourth event of the CHAU-SHI Series. The champion receives NT$1 million, with NT$450,000 awarded to the runner-up and NT$220,000 to the third-place finisher.

In addition to players from host nation Chinese Taipei, the tournament featured professionals from six other countries and regions—Italy, Japan, Malaysia, the Philippines, Thailand, and the United States. The field consisted of 129 professional golfers, including 104 Taiwanese professionals, along with 14 Taiwanese amateurs competing in the event.

The CHAU-SHI Series was initiated by Mr. Chao-Hsi Weng, one of the founders of Mercuries & Associates and Honorary Chairman of the Mercuries Group. Beginning in 2021, when the COVID-19 pandemic significantly reduced both the number of TPGA Tour events and total prize money, Mr. Weng personally became the overall title sponsor of the series. He funded six tournaments, contributing NT$2 million to each event, for a total of NT$12 million, helping establish the foundation of the 2021 TPGA Tour schedule.

This year marks the sixth consecutive year that the series has been held under the same sponsorship model. Each tournament in the CHAU-SHI Series receives NT$1.5 million in sponsorship from Mr. Weng, with eight tournaments scheduled for the 2025 season.

The CHAU-SHI Series also features a special Season Money Title Award. The player who finishes as the series' leading money winner will receive an additional NT$250,000, sponsored by Lin Kuo-er, Chairman of Hong Lin Construction Co., Ltd., as well as an exemption into the following year's Mercuries Taiwan Masters.

Wei Chao-liang, General Manager of Double Oaks Development Co., Ltd., stated that the company's continued support of TPGA events and its annual increases in prize money stem from long-term insights into customer preferences. Double Oaks' clientele primarily comes from the top 10 percent of consumers in the Taichung, Changhua, Nantou, Miaoli, and Yunlin-Chiayi regions. Company research has shown that more than half of its target customers regularly play golf.

Wei explained that by helping elevate the standard of professional tournaments, Double Oaks hopes to provide Taiwanese professionals with a more competitive platform while offering direct support to the development of the sport. In addition to sponsoring TPGA tournaments, the company has also been the long-term title sponsor of community Super Slow Jogging events, reflecting its commitment to promoting sports culture and public health as an important part of urban lifestyle development.

Wei further noted that although Double Oaks is a real estate developer, the company has always regarded itself as an "integrator of premium lifestyles." For many years, it has invested heavily in creating comprehensive services covering food, fashion, housing, transportation, education, leisure, and wellness.

For TPGA players as well as its residents, Double Oaks strives to provide complete, high-quality services. In the area of dining, the company operates the highly acclaimed Din Yue Restaurant. In fashion, it serves as the exclusive Taiwan distributor for the global luxury brand Giorgio Armani. In transportation, it maintains a fleet of seven premium chauffeur vehicles, providing transportation and professional vehicle care services for residents. In the fields of recreation and health, its You Young Sports Club has established a Professional Sports Recovery Center at the tournament venue, offering professional sports therapy and recovery services to players and distinguished guests throughout the event.

The corporate philosophy of Double Oaks Development mirrors the growth journey of every professional golfer—building strength and reputation step by step. Since its establishment in 2004, the company has earned an outstanding reputation through high-quality construction and attentive customer service. In 2018, it took another significant step by establishing its own property management company, marking a turning point in its mission to enhance residents' quality of life.

Over the past eight years, the company has grown to 160 employees, providing frontline services across five residential communities. Thanks to its strong reputation within the industry, Double Oaks has attracted many highly qualified professionals, allowing employees to fully utilize their expertise while achieving a strong sense of accomplishment, creating a win-win environment for both the company and its workforce.

It was precisely because Double Oaks established its own property management company and focused on proactive planning that many of its subsequent business ventures became possible.

Wei Chao-liang explained that the company initially introduced six daily meal services within its residential communities. As resident demand continued to grow, this ultimately led to the establishment of Din Yue Restaurant. Likewise, what began as community chauffeur services gradually expanded into premium offerings such as professional car detailing, beauty, skincare, and nail care services. Each year, the company carefully evaluates residents' evolving needs and plans ahead to meet future expectations—a philosophy that closely parallels the mindset of professional golfers, who continually challenge themselves to reach higher levels of performance.

The core values of Double Oaks Development are "Architecture, Art, and Better Living." While supporting TPGA tournaments as a title sponsor, the company also continues to learn, innovate, and improve itself, just as professional golfers do.

Professional golfers strive to overcome challenges and improve with every tournament, recognizing that their greatest opponent is ultimately themselves. This philosophy closely aligns with Double Oaks' commitment to continual self-improvement, understanding customers' needs, and constantly pursuing higher standards of service.
