Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
sach ty » sach y, sach tu, sach thu
dai hau » dai han, dai hai, hai hau
dai huu » dao huu, dai thua, dai thuc
va hanh » van hanh, va danh, ban hanh
cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua
ty nang » ky nang, ty xang, ty hang
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang x hoi. hieu va cac xuc ((va hanh) or (va thanh)) ((dai huu) OR (dai hau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang x hoi. hieu va cac xuc ((va hanh) OR (va thanh)) ((dai huu) OR (dai hau)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. hieu va cac xuc ((va hanh) or (va thanh)) ((dai huu) OR (dai hau)) tre*".
