Perhaps you should try some spelling variations:
thien van » thi van
van hac » van hoc, van ha, van hai
hac tuc » thac toc, thai tuc
xa hanh » xa thanh, xa khanh, va hanh
hoi cua » hoi chuc
tu dan » tuc dan, tu ban, tu can
cu dan » cua dan, ca dan, co dan
x hoi » xa hoi, o hoi, x ho

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: ((tu dan) OR (cu dan)) ky nang x hoi. thien van hac tuc xa hanh ((dai cua) OR (hoi cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: ((tu dan) or (cu dan)) ky nang x hoi. thien van hac tuc xa hanh ((dai cua) or (hoi cua)) tre*.
