Perhaps you should try some spelling variations:
thanh doi » thanh loi, thanh moi, thanh do
ban thanh » ban hanh, ban hang
cau tren » cu tren, dau tren, ca tren
cham xuc » chat xuc, cham soc, pham duc
doi cau » doi dau, di cau, doi ca
sach va » sach xa, sach dao, sach nha
nang ma » tang ma, sang ma, nang cao
sach ha » sach nha, sach han, sach xa
hieu ve » hieu va, hieu van
ma hoi » mai hoi, xa hoi, ma hoa

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: su ((sach va) OR (sach ha)) nang ma hoi. hieu ve ((cham xuc) OR (cam xuc)) ban thanh doi cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach va) OR (sach ha)) nang ma hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh doi cau tren~".
• Adding a wildcard symbol may retrieve word variants: su ((sach va) OR (sach ha)) nang ma hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh doi cau tren*.
