Perhaps you should try some spelling variations:
vu chat » va chat, ve chat, du chat
lai hoi » dai hoi, lai roi, mai hoi
lai hoa » dai hoa, loai hoc
hieu vu » hieu va, hieu ve, hieu su
ky sang » ky nang, ky dang, ky tang
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua, di cua
tu van » tu va
xuc va » duc va, luc va, xac va
cua te » cua tu

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 van ky sang ((lai hoi) OR (lai hoa)). hieu vu chat ((xuc va) OR (tuc va)) hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky sang ((lai hoi) or (lai hoa)). hieu vu chat ((xuc va) OR (tuc va)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu van ky sang ((lai hoi) or (lai hoa)). hieu vu chat ((xuc va) OR (tuc va)) hanh vi cua te*.
