Bu Yunchaokete on his tactics vs Kachanov

Bu Yunchaokete on his tactics in the surprising win over Karen Khachanov "On one hand, as the match progressed, I did my best to adjust to his serves; at the same time, I focused more on my own service games. His serve was extremely difficult to break, and once I lost my serve, it became hard to win, so my priority was to hold my own serve."
