Perhaps you should try some spelling variations:
va trien » va truyen, va thiet, va tuyen
cham xuc » cam xuc, chat xuc, cham soc
ve triet » su triet
ban hang » ngan hang
su sach » so sach, vu sach
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
sach v » sach va, sach y, sach 2
nang o » nang co, nang ho, nang ro
v nang » va nang, vu nang, van nang
o hoi » co hoi, o hoc, o hai

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 v nang o hoi. hieu ve cham xuc ((van ban) or (ban hang)) vi ((ve triet) OR (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang o hoi. hieu ve cham xuc ((van ban) OR (ban hang)) vi ((ve triet) OR (va trien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang o hoi. hieu ve cham xuc ((van ban) or (ban hang)) vi ((ve triet) OR (va trien))".
• Adding a wildcard symbol may retrieve word variants: su sach v nang o hoi. hieu ve cham xuc ((van ban) or (ban hang)) vi ((ve triet) OR (va trien))*.
