Perhaps you should try some spelling variations:
thien van » thi van
hoc cac » hoc cao
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
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: hoc cac ky nang xa hoi. ((hieu va) OR (thien van)) cam xuc va hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: hoc cac ky nang xa hoi. ((hieu va) or (thien van)) cam xuc va hanh vi cua tre*.
