Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
qua cham » qua hai, qua cac, va cham
cua tre » cua te, cuu tre, cua triet
su van » vu van
tu van » tu va
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
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: ((su van) OR (tu van)) ky nang x hoi. hieu qua cham ((xuc va) OR (luc va)) thanh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su van) or (tu van)) ky nang x hoi. hieu qua cham ((xuc va) OR (luc va)) thanh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su van) or (tu van)) ky nang x hoi. hieu qua cham ((xuc va) OR (luc va)) thanh dai cua tre*.
