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

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