Perhaps you should try some spelling variations:
cach thuc » anh thuc
hanh dai » hanh tai, hanh dao, vanh dai
van hanh » van thanh, ban hanh, van anh
sach thu » sach thue, sach thieu, sach tham
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
cac thu » cac thoi
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac
cua tu » cua tuc, cua su, cua cu

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 thu) OR (((cach thuc) OR (cac thu)))) nang ma hoi. hieu ve cac xuc van hanh dai cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach thu) or (((cach thuc) OR (cac thu)))) nang ma hoi. hieu ve cac xuc van hanh dai cua tu~".
• Adding a wildcard symbol may retrieve word variants: te ((sach thu) or (((cach thuc) OR (cac thu)))) nang ma hoi. hieu ve cac xuc van hanh dai cua tu*.
