Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
dai cau » dat cau, da cau, dao cau
dai hau » dai han, dai hai, dai huu
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. lieu va cac xuc ((va hanh) or (gia thanh)) ((dai cau) OR (dai hau)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang x hoi. lieu va cac xuc ((va hanh) OR (gia thanh)) ((dai cau) OR (dai hau)) tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. lieu va cac xuc ((va hanh) or (gia thanh)) ((dai cau) OR (dai hau)) tren*".
