Perhaps you should try some spelling variations:
cham luc » cham soc, nhan luc, cham cuu
hieu van » hieu va, thien van, lieu va
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va
sai ky » sac ky
vi cua » vai cua, di cua
tu sai » tu bai, tu san, tu cai
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: tu sai ky nang x hoi. ((hieu ve) OR (hieu van)) cham luc ((va hanh) OR (va danh)) vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang x hoi. ((hieu ve) or (hieu van)) cham luc ((va hanh) or (va danh)) vi cua tre*.
