Taiwanese boxer Yu Che Li - https://boxrec.com/en/box-pro/776625 - fought an unknown opponent on this show https://boxrec.com/en/event/790019. There are many images of the bout here - http://sportsphoto.cn/img.html?group_id ... 018&page=3 (you can navigate between photos with the arrows). The site lists the opponent as Waldo Sabu - https://boxrec.com/en/box-pro/598500. The shorts of the opponent also match very closely with a fight Sabu had 6 months later, video of that fight here - https://www.dailymotion.com/video/x7p81vw. Sabu had also fought for the same promoter in the past. If there's something I'm missing let me know but everything I've found points to Sabu being the opponent.
Sorry for all the links, I just wanted to make sure I have all my bases covered.
