yang yang » wang yan
huang lin » huang bin, huang jing, huang ting
dang hadi » dang hai
hua gene » human gene, a gene, hua ren
lin dang » bin dann, ein dank, le dang
ka hua » ya hua, ka chuan

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 yang) OR (yang yang)) ka hua gene huang lin dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang yang)) ka hua gene huang lin dang hadi ;*.
