Perhaps you should try some spelling variations:
dua tren » dung tren
thanh vi » hanh vi, thanh va, thanh ve
toc sach » hoc sach, doc sach, thuoc sach
va thanh » gia thanh, ban thanh, va tinh
cham xuc » cam xuc, chat xuc, pham duc
hieu va » lieu va, hieu qua
vi dua » vi du, vi dum, vi lua
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: ((te sach) OR (toc sach)) ky nang x hoi. hieu va ((cham xuc) OR (cham soc)) va thanh vi dua tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ky nang x hoi. hieu va ((cham xuc) OR (cham soc)) va thanh vi dua tren~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (toc sach)) ky nang x hoi. hieu va ((cham xuc) OR (cham soc)) va thanh vi dua tren*.
