Perhaps you should try some spelling variations:
enwei shen » wei shen
wan liang » wang liang, yan liang, yang liang
kwei shen » kwei sheng, wei shen
chang won » chang soon, chang ann, chang min
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) OR (enwei shen)) chang won ((shang hai) OR (wang yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "daud wan liang ((kwei shen) OR (enwei shen)) chang won ((shang hai) or (wang yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: daud wan liang ((kwei shen) OR (enwei shen)) chang won ((shang hai) or (wang yue)) ;*.
