Chiau enters the Forbidden City as an undercover agent disguised as a eunuch, becoming involved in a complicated Ching vs Ming plot. Wonderful spoof of Jin Yong style wu xia pian, with manic plotting and martial arts. The action from Ching Siu-Tung is some of his best work, featuring wild and insane choreography that really brings the kind of supernatural martial arts skills Jin Yong wrote about to life. You also get Stephen Chiau being very funny - a great combination, and probably my favourite Chiau film prior to Shaolin Soccer.

*edit* after revisiting, part 1 is definitely the lesser of the two films - too much juvenile humour and relatively little plot progression. Part 2 definitely picks up though.
