Perhaps you should try some spelling variations:
kwei sheng » wei shang
chan kang » chung kang, chan eng, chan fong
kang kwei » wang wei, fang wei
shang hai » shang kai, dang hai, chang ha
tas chan » gas chain, say chan, tas tan
yang jin » yang jie, yang jun, ying jin
yang xi » yang jui
yang yi » yang jui

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: tas chan kang kwei sheng ((((((yang xi) OR (yang jin))) OR (yang yi))) OR (yang di)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tas chan kang kwei sheng ((((((yang xi) or (yang jin))) or (yang yi))) or (yang di)) shang hai ;*.
