Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
cham xuc » cam xuc, chat xuc, pham duc
va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
cua tre » cua te, cuu tre, cua triet
su van » tu van, vu van

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 ky ((nang xa) OR (nang ma)) hoi. hieu qua ((cham xuc) OR (cham soc)) va thanh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su van ky ((nang xa) OR (nang ma)) hoi. hieu qua ((cham xuc) or (cham soc)) va thanh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su van ky ((nang xa) OR (nang ma)) hoi. hieu qua ((cham xuc) or (cham soc)) va thanh dai cua tre*.
