Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
tay lang » tai lang, tay quang, tham lang
tay tang » tay trung, tay quang, tay tieng
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
cua tre » cuu tre, cua triet, dua tren
hanh di » hanh vi, hanh de, hang di
hieu va » lieu va, hieu qua
cua te » cua tu
va am » va lam, va cam

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 ((tay lang) OR (tay tang)) xa hoi. hieu va am thuc van hanh di ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tay lang) OR (tay tang)) xa hoi. hieu va am thuc van hanh di ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: te sach ((tay lang) OR (tay tang)) xa hoi. hieu va am thuc van hanh di ((cua tre) or (cua te))*.
