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
tai cuu » tai cuc, tai buu, tai cua
va hanh » van hanh, va danh, ban hanh
cuu tre » cua tre, cau tren, cau treo
cac xuc » cac nuoc, chat xuc, cac cuoc
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang

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 xa hoi. hieu va ((cac xuc) or (cam xuc)) ((va hanh) OR (va thanh)) tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. hieu va ((cac xuc) OR (cam xuc)) ((va hanh) OR (va thanh)) tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu va ((cac xuc) or (cam xuc)) ((va hanh) OR (va thanh)) tai cuu tre*".
