Perhaps you should try some spelling variations:
hieu hien » bieu hien, dieu hien, chieu chien
khach ky » hanh ky, thanh ky
vu khach » vu khanh, vu khac, vay khach
hien cac » thien cac, vien cac, hieu cac
truc va » thuc va, thuc vat, trung va
nang xa » nang x, lang xa, nang ma
lai cua » dai cua, hai cua, lai chau
tuc va » thuc va, tuc xa, duc 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: vu khach ky nang xa hoi. hieu hien cac ((tuc va) OR (truc va)) thanh ((vi cua) OR (lai cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach ky nang xa hoi. hieu hien cac ((tuc va) OR (truc va)) thanh ((vi cua) or (lai cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: vu khach ky nang xa hoi. hieu hien cac ((tuc va) OR (truc va)) thanh ((vi cua) or (lai cua)) triet*.
