Perhaps you should try some spelling variations:
cuu tre » cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua tre » cua te, cua triet, dua tren
danh vi » hanh vi, dinh vi, danh di
tu sac » tu sach, tu cac, tu san
loc va » hoc va
sac ky » cac ky, sai ky
luc va » duc va, tuc va
ve cam » ve cham, ve cac, va cam

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu ve cam ((luc va) OR (loc va)) danh vi ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve cam ((luc va) OR (loc va)) danh 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 ((luc va) OR (loc va)) danh vi ((cua tre) or (cuu tre))*".
