Perhaps you should try some spelling variations:
cham luc » cham soc, nhan luc, cham cuu
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
nang ma » tang ma, sang ma, nang cao
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, ma hoa
sach v » sach va, sach 2, sach vay
va dan » ca dan, va dao, va dap
va dau » va dao
vi cua » vai cua, di cua

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 v) OR (sach y)) nang ma hoi. hieu ve cham luc ((va dan) OR (va dau)) vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach y)) nang ma hoi. hieu ve cham luc ((va dan) or (va dau)) vi cua tre*.
