chang hai » chang ha, shang hai, change has
tan yang » dan yang, tan ying, tan yong
yao yang » yang yang
ning ji » ying jin, jing jia, ping jia
jing ji » ying jin
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((ning ji) OR (jing ji)) ((((tan yang) or (tan hong))) or (yao yang)) china chang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((ning ji) OR (jing ji)) ((((tan yang) OR (tan hong))) OR (yao yang)) china chang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((ning ji) OR (jing ji)) ((((tan yang) or (tan hong))) or (yao yang)) china chang hai ;*".
