Perhaps you should try some spelling variations:
wang yang » wang yan, wang yanling
gene tang » gene bank
min jeong » kin keong, min hong, mun leong
jeong ghi » hong ghi, jeong mi
tan chia » tuan china, than china, can china
tang min » chang min, sang minh, yang mind
tan zhi » yan zhi, wang zhi

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: ((wang liang) OR (wang yang)) ((tan zhi) OR (tan chia)) gene tang min jeong ghi ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yang)) ((tan zhi) or (tan chia)) gene tang min jeong ghi ;*.
