Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh oai
thanh tai » thanh hai, thanh toan, doanh tai
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van lam » van nam
cua tre » cua te, cuu tre, cua triet
su xac » pu xac, su cac
xac ky » cac ky, sac ky, bac ky
xuc va » tuc va, luc va, xac va

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

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