Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
chat xuc » chat huu, chao xu, chat cua
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty lang » tay lang, ty xang, ty hang
lang xa » lang ha, dang xay, lang van
cua tre » cuu tre, cua triet, dua tren
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu van ((chat xuc) OR (cam xuc)) van hanh vi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu van ((chat xuc) OR (cam xuc)) van hanh vi ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu van ((chat xuc) OR (cam xuc)) van hanh vi ((cua tre) or (cua te))*.
