Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
te sai » te tai, te bai, te lai
sai ky » sac ky
ve cam » ve cham, ve cac, va cam
di cua » dai cua, doi cua, de cua
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 sai ky nang x hoi. hieu ve cam xuc ((va hanh) OR (va danh)) di cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sai ky nang x hoi. hieu ve cam xuc ((va hanh) or (va danh)) di cua tre*.
