The trio sit one shot clear of defending champion Kazuki Higa, Chinese-Taipei’s Wei-hsuan Wang and New Zealander Denzel Ieremia, who all opened with 65s on a day of low scoring.

Chang produced the most eventful of the three rounds, making nine birdies and a solitary bogey to take the clubhouse lead in the morning before Tangkamolprasert and Hung matched his score in the afternoon.

The 28-year-old Malaysian arrived in strong form after winning the Port Dickson Championship on his home tour in August by seven shots.

But his 64 was anything but straightforward.

“My putting and my damage control overall were key today,” said Chang.

“On hole number seven, my 16th basically as I started on back nine, I actually duffed my tee-shot. Then I had 185 yards to the pin, into the wind, and hit a six iron to 18 feet and made it for birdie.

“On hole number nine, my last hole, I hit my tee shot a little bit left, but the second shot caught a flyer over the green, but I chipped in for birdie. Earlier on three I also chipped in for birdie.

“There were some crazy moments, some moment that just made me wonder, like, am I doing this correctly?”.

Chang has also been cutting back on golf-related social media, choosing not to look at golf content after his rounds.

“I didn't look at the scoreboard, and it's something that I've been working on over the last three months. I didn't cut off social media, but I cut off golf on my social media, on my Instagram, as just because on the golf course it is stressful enough, and I don't look at golf again after the round.”

Tangkamolprasert matched Chang’s score without dropping a shot, making an eagle and six birdies.

The two-time Asian Tour winner had an extra reason to perform with his wife, Thai LPGA professional Chorphaka Jaengjit, watching on during their 20th anniversary week.

“This week is our 20th anniversary of being together. So, it is a very special week for me. I am trying to win for her.”

Hung also made an eagle and seven birdies, but dropped his only shot of the day on his final hole after battling calf cramps over the closing stretch.

“I bogeyed the last, but I told myself it’s ok,” said Hung.

“I think the main highlight today was how I played through my calf cramps on the last three holes! I was just thinking about how I got it. Did I not drink enough water? Maybe because the weather is cooling that’s why I thought I didn’t need to drink too much.

“I knew it’s easy to make bogeys on the last three holes, so I wasn’t expecting too much. Because of the cramps, I wasn’t able to concentrate as well. I actually had an easy chip on the last, but I didn’t chip well which was a pity. But overall, it’s alright.”

Hung is chasing his maiden Asian Tour title after winning the Ambassador ADT Open on home soil in July, with his wife Nikki back on the bag for the first time since giving birth to their son earlier this year.

Defending champion Higa is also in the mix after opening with a 65. Last year’s victory at Linkou helped propel him to the Asian Tour Order of Merit title, but he currently sits 113th.

“I know the winner of the Order of Merit will earn a DP World Tour card, but I will see how this week goes before I think about that.”

Higa made five consecutive birdies from the ninth.

“It feels like my second home, especially as I am sponsored by Yeangder. A lot of people here are cheering for me, so I am trying to manage and enjoy it,” he said.

“I struggled off the tee but had some lucky breaks. From the fairway, my wedges were dialled in. Just off the tee it wasn’t stable. I will try and fix it today.”

Malaysia’s Khavish Varadan and Thailand’s Jazz Janewattananond are among a large group tied for seventh at six-under, while Australian Travis Smyth and Hong Kong’s Taichi Kho both opened with 68s.
