Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
ban hang » ngan hang
sach ly » sach y, sach lo, sach ty
su sach » so sach, vu sach
du chat » duoc chat, dung chat, doc chat
hieu du » hien du, hieu su, hiem du
ly nang » ky nang, ly hang, ly vang
x hoi » xa hoi, o hoi, x ho
ve ve » de ve, va ve, ve ke
ke ve » ke va, ke he, de ve

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly nang x hoi. hieu du chat xuc ((van ban) or (ban hang)) ((ve ve) OR (ke ve)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly nang x hoi. hieu du chat xuc ((van ban) OR (ban hang)) ((ve ve) OR (ke ve)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly nang x hoi. hieu du chat xuc ((van ban) or (ban hang)) ((ve ve) OR (ke ve)) triet*".
