amin hong » min hong, among hong, tin hong
yang yao » wang yan, yang yi, yang fan
hua shen » han shen, hua ren, jia shen
hua chen » jui chen, yu chen, a chen
hong hai » shang hai, zhong tai, dang hai

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: ((((yang yao) OR (yang yang))) OR (yang di))ng ya ((hua shen) OR (hua chen)) chang amin hong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yao) OR (yang yang))) or (yang di))ng ya ((hua shen) or (hua chen)) chang amin hong hai ;*".
