Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
thanh vai » thanh van, thanh tai, thanh oai
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, cua triet
lam xuc » cam xuc, lam duoc
van lam » van nam
lang xa » lang ha, dang xay, lang van
xac ky » cac ky, sac ky
xuc va » duc va, tuc va, luc va
bac ky » cac ky, ban ky, sac ky

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