Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
ky lang » ky dang, ky tang, tay lang
van cam » van nam, van cau, van dam
van lam » van nam
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac, su xac
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky lang) OR (ky nang)) xa hoi. hieu ((van cam) or (van lam)) xuc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky lang) OR (ky nang)) xa hoi. hieu ((van cam) OR (van lam)) xuc va thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky lang) OR (ky nang)) xa hoi. hieu ((van cam) or (van lam)) xuc va thanh vi cua tre*".
