Perhaps you should try some spelling variations:
liang kwei » liang wei, xiang wei
kwei sheng » wei shang
wan liang » wang liang, yan liang, yang liang
chang won » chang soon, chang min, chang you
chang ann » chang min, chang yun, change annex
shang kai » shang hai
daud wan » dato wan
hong yu » wong yue

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: daud wan liang kwei sheng ((chang won) OR (chang ann)) ((shang kai) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "daud wan liang kwei sheng ((chang won) OR (chang ann)) ((shang kai) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: daud wan liang kwei sheng ((chang won) OR (chang ann)) ((shang kai) or (hong yu)) ;*.
