Perhaps you should try some spelling variations:
cau phuc » cau truc, chau phu, huu phuc
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
phuc va » phuc vu, thuc va, chuc va
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, cua triet
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: tu cac ky ((nang xa) OR (van xay)) hoi. ((hieu ve) OR (hieu va)) cau phuc va danh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((nang xa) or (van xay)) hoi. ((hieu ve) or (hieu va)) cau phuc va danh vi cua tre*.
