hum kiu (chen qiao, sinking bridges), follows the siu lien tao in the curriculum. Similar to side punch and arrow punch that follow the meridian punch of the sup yee sik, this set integrates the basic motions with turning and stepping and works on developing attack and defense in all four directions.

While the name of the form can refer to “sinking (rooting)”and “bridging (joining)”, it is also relates to the concept of “sinking the (opponent’s) bridge”, or, in other words, destroying their structure. The chum kiu form itself introduces kicking techniques such as heart piercing kick and side nailing kick. It also contains several different versions of the wing arm, both sweeping and throwing, performed at high, middle, and low levels, as well as versions of the barring arm, neck detaining arm, and other techniques. As with the siu lien tao, this set is also commonly known by the name chum kiu (xun qiao, seeking bridges).
