There are three Chan Wan entries on the db. Their chinese character are not the same but are quite similar. I think they could be the same person.

According to Hong Kong Filmography Vol. IV, where there's just one Chan Wan credited, the correct chinese name should be the first.

The second problem is the fact that Chan Wan used several nicknames during his career, such as Auyeung Man-wai or Lau Cheung-ching.

From the same source it seems that at least another movie should be credited to him as director:
Colourful Youth (1966)
