Easter is not widely celebrated in China, but it's known in urban areas and among Christians. The Chinese name perfectly captures the religious meaning — 复活 (resurrection) + 节 (festival).
memory
复活 (fùhuó) means 'resurrection/to come back to life' and appears in many contexts: 复活节 (Easter), 复活赛 (repechage/playoff), or in games when a character respawns.
