Perhaps you should try some spelling variations:
chang kwok » chang deok, chang won
wang yang » wang yan, wang liang, wang yanling
phan shen » han shen, than she
khan sher » han shen, khan syed, than she
kwok wong » kok wing
yang dan » yang dean, yang fan, wang dan
wong yue » wang yue, hong yu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang dan ((phan shen) OR (khan sher)) chang kwok wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang dan ((phan shen) OR (khan sher)) chang kwok wong yue ;*".
