On December 14, 2025, the WBC MuayThai Greater China (Hong Kong) National Super Bantamweight Championship was contested in Hong Kong, as hometown fighter Tsang Sik Hei faced China’s Zhang Gu-Yin in a highly competitive and intense title bout.
Tsang Sik Hei began the contest assertively in the opening round, pressing forward with an aggressive game plan. He employed sharp punching combinations and a steady series of kicks, with his low kicks proving particularly effective in disrupting Zhang Gu-Yin’s base and limiting his early offense. Tsang’s forward pressure allowed him to control much of the opening exchanges.
In the second round, Zhang Gu-Yin made clear tactical adjustments. Shifting to a more composed, counterattacking approach, he closed the distance and began working effectively in the clinch. Zhang used elbows and knee strikes to challenge Tsang’s momentum, looking to turn the tide. Tsang responded well, defending intelligently and landing counters of his own, keeping the bout closely contested.
The pivotal moment came in the third round when Zhang Gu-Yin landed a clean elbow strike that opened a cut on Tsang Sik Hei’s forehead. The injury caused significant bleeding, prompting close monitoring by the ringside medical team as the action continued.
Following further assessment, the bout was stopped at 1:01 of the fourth round on the advice of the ringside doctor and referee due to the worsening cut. As a result, Zhang Gu-Yin was declared the winner and awarded the WBC MuayThai Greater China (Hong Kong) National Super Bantamweight Title.
The contest highlighted the strengths of both athletes, with Tsang Sik Hei demonstrating strong early aggression and Zhang Gu-Yin showcasing adaptability, composure, and effective use of close-range techniques. Although the match concluded via medical stoppage, both fighters displayed high-level skill and determination throughout the championship bout.
