Coaching Hidilyn Diaz Gao Kaiwen was recruited to coach Hidilyn Diaz of the Philippines two months prior to the 2018 Asian Games in Jakarta, Indonesia where Diaz clinched a gold medal. He also introduced new routines and heavier weights in Diaz's training. Gao was joined in by other coaches and officials including second coach Julius Naranjo. Diaz's coaching staff became known as "Team HD".

In a lead up to the 2020 Summer Olympics, which was later postponed by a year due to the COVID-19 pandemic, Diaz went to Malaysia in February 2020 following the advice of Gao so she could be more focused in qualifying for a berth in the Olympics. Diaz managed to qualify but Diaz was forced to spend most of her time training in Malaysia due to logistical issues posed by COVID-19 related travel restrictions.
