Perhaps you should try some spelling variations:
chang wei » zhang wei, wang wei, chang gui
dang hadi » dang hai
tan ying » fan ying, ran ying, tan yong
tan yang » dan yang, tan yong, tao yang
wei chen » wei shen, frei chen, jui chen
yang jui » yang judy, yang di, yang xi
yang yi » yang di, yang xi

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: ((tan ying) OR (tan yang)) chang wei chen ((yang jui) OR (yang yi)) dang hadi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan ying) OR (tan yang)) chang wei chen ((yang jui) or (yang yi)) dang hadi ;~".
• Adding a wildcard symbol may retrieve word variants: ((tan ying) OR (tan yang)) chang wei chen ((yang jui) or (yang yi)) dang hadi ;*.
