Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, le thanh
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
van lam » van nam
lam xuc » cam xuc, lam duoc
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
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: tu cac ((ky lang) or (ky dang)) xa hoi. hieu van lam xuc ((va thanh) OR (va tinh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc ((va thanh) OR (va tinh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((ky lang) or (ky dang)) xa hoi. hieu van lam xuc ((va thanh) OR (va tinh)) vi cua tre*".
