Perhaps you should try some spelling variations:
thuoc sach » nuoc sach, thuat sach, thuoc sinh
hoc sach » hoc sinh, hoc cac, hoc anh
hanh ve » hanh vi, hanh va, hanh kem
va hanh » van hanh, va thanh, va danh
cac xuc » cac nuoc, chat xuc, cac cuoc
hieu va » lieu va, hieu qua
nang co » nang cao, nang doc, nang noi
ca tren » cau tren, cu tren, la tren
co hoi » co hoc, co loi
ve ca » ve cac, ve cai, ve cau

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: ((thuoc sach) OR (hoc sach)) ky nang co hoi. hieu va ((cac xuc) OR (cam xuc)) va hanh ve ca tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) OR (hoc sach)) ky nang co hoi. hieu va ((cac xuc) or (cam xuc)) va hanh ve ca tren~".
• Adding a wildcard symbol may retrieve word variants: ((thuoc sach) OR (hoc sach)) ky nang co hoi. hieu va ((cac xuc) or (cam xuc)) va hanh ve ca tren*.
