Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
chat xuc » chat huu, cam xuc, chao xu
cham xuc » cam xuc, cham soc, pham duc
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
hieu ve » hieu va, hieu van
vu dang » su dang, vu quang, cua dang
v nang » va nang, vu nang, van nang
vi cua » vai cua, di cua
cua te » cua tu

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: toc sach ((v nang) OR (vu dang)) xa hoi. hieu ve ((cham xuc) OR (chat xuc)) va danh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((v nang) or (vu dang)) xa hoi. hieu ve ((cham xuc) OR (chat xuc)) va danh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: toc sach ((v nang) or (vu dang)) xa hoi. hieu ve ((cham xuc) OR (chat xuc)) va danh vi cua te*.
