Chum Kiu is translated as 'searching for the bridge', and is the Wing Chun intermediate level form. After a proficient level is attained in the Siu Nim Tau, Chum Kiu is taught. Jyun Ma - Turning Stance, Hau Ma - Back Stance, are incorporated using Yiu Ma - Waist Power, to generate force in the strikes and block movements. The Wing Chun kicks are also introduced at this stage, however further kicking drills are taught to maintain correct hand positions as learnt in the Siu Nim Tau.

Chum translates as search or 'to seek', and Kiu has the meaning bridge, Kiu Sau therefore has the meaning 'Bridge Hand'. Knowing how to deal with an opponent's bridges ( arms ) is needed, hence the Chi Sau training which trains sensitivity which is seriously required at this stage. The heart of the Chum Kiu form is 'Yiu Ma Hap Lap', translated as 'waist power co-operation', either in deflecting or returning force.
