Perhaps you should try some spelling variations:
chung chuan » chen chuan
chang chung » chang ch'un, chang chen, chang chuan
yang yang » wang yang, wang yan
zhong zhi » zhang zhi, hong ghi, zhong tai
yang yao » wang yan, yang fan
yi chang » ii chang, ying chang, jin chang
yang yi » yang di, yang xi, yang jui

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)) yang yi chang chung chuan ((cong shu) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yao) OR (yang yang)) yang yi chang chung chuan ((cong shu) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yao) OR (yang yang)) yang yi chang chung chuan ((cong shu) or (zhong zhi)) ;*.
