Perhaps you should try some spelling variations:
thien van » thi van
cau tren » cu tren, dau tren, ca tren
su sach » so sach, vu sach
nang ma » tang ma, sang ma, nang cao
van cam » van nam, van lam, van cau
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
xuc va » duc va, tuc va, luc va
vi cau » va cau, ve cau, di cau

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 sach y ((nang ma) OR (mang may)) hoi. thien van cam xuc va danh vi cau tren~.
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang ma) or (mang may)) hoi. thien van cam xuc va danh vi cau tren*.
