Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh ve, nhanh vi
thanh va » thanh van, hanh va, thanh ha
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam tu » cam thu, nam tu, dam tu
sai ky » sac ky
ve cam » ve cham, ve cac, va cam
tu sai » tu bai, tu san, tu cai

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