han shen » khan sher, can she, han en
hong ghi » zhong zhi, hong g, hong hai
wan yan » wang yan, nan yan, wai yan
yan yan » yan yuan, nan yan, yang yang
hua ren » hua chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan yan ((hua ren) or (han shen)) ((chang mae) OR (changes made)) hong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan yan ((hua ren) OR (han shen)) ((chang mae) OR (changes made)) hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yan ((hua ren) or (han shen)) ((chang mae) OR (changes made)) hong ghi ;*".
