Soy bean vendor Sha'er is forced to use his unique kung fu skills against community bullying by local hooligan Sanye and his thugs. Sha'er's special Huixnquan-style kung fu was practiced by Buddhists in the earlier Qing dynasty under the mantra "no matter what changes, we can adapt to it". This particular kung fu featured the use of the proponent's long plait of hair in self-defense which Sha'er puts to good use against the thugs. He is then recruited to the HuCheng Battalion to train soldiers in kung fu and leads them in battles to rebel against the influence of the western foreigners in their country.
