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

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 ((cua tre) or (cua te))~.
• 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 ((cua tre) OR (cua te)).
• 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 ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su ((xac ky) OR (bac ky)) lang xa hoi. hieu van lam xuc va thanh vai ((cua tre) or (cua te))*.
