Chung-Hsing Liu has found hard courts difficult, recording 7–10 across 17 matches (41.2%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

By format on hard — best-of-five: 4–7 (36.4%); best-of-three: 3–3 (50.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.
