yang liang » wang liang, yan liang, yang yang
a soybean » _ soybean, 4 soybean, _ soybeans
zhong tai » hong tan, hong hai, zhong zhi
yang jui » yang judy, yang xi, yang yi
man a » man ja, oman a, man _
kann » ann

You may be able to get more results by adjusting your search query.

• Adding a wildcard symbol may retrieve word variants: kann man a soybean grain ((yang liang) or (((yang jui) or (yang di)))) zhong tai ;*.
