Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va

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 sac ky nang xa hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua tre) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua tre) or (cuu tre))*.
