shang kai » shang hai
dang hari » dang hai
ran ying » fan ying, tan ying, jin ying
wei chen » frei chen, jui chen, yi chen
wei shen » kwei sheng, enwei shen, wei shang
yang yi » yang xi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ran ying yang ((wei chen) OR (wei shen)) ((yang di) or (yang yi)) ((shang kai) or (dang hari)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ran ying yang ((wei chen) OR (wei shen)) ((yang di) OR (yang yi)) ((shang kai) OR (dang hari)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran ying yang ((wei chen) OR (wei shen)) ((yang di) or (yang yi)) ((shang kai) or (dang hari)) ;".
• Adding a wildcard symbol may retrieve word variants: ran ying yang ((wei chen) OR (wei shen)) ((yang di) or (yang yi)) ((shang kai) or (dang hari)) ;*.
