Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cham xuc » chat xuc, cham soc, pham duc
cau tren » cu tren, dau tren, cau treo
thanh di » thanh doi, thanh de, thanh do
tu sach » thu sach, su sach, te sach
sach va » sach xa, sach ha, sach dao
ca tren » cu tren, la tren, co tren
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, nang cao
va nang » van nang, da nang, cam nang
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: tu sach va nang ma hoi. hieu ve ((cham xuc) OR (cam xuc)) ban thanh di ((cau tren) OR (ca tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach va nang ma hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh di ((cau tren) OR (ca tren))~".
• Adding a wildcard symbol may retrieve word variants: tu sach va nang ma hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh di ((cau tren) OR (ca tren))*.
