Perhaps you should try some spelling variations:
vu sach » vu bach, su sach, vu khach
hieu ve » hieu va, hieu van
xuc gia » duc gia, tuc gia, quoc gia
luc gia » luoc gia, duc gia, quoc gia
lap cua » tap cua, lam cua, ap cua
lai cua » dai cua, hai cua, lai chau
y nang » ky nang, ly nang, v nang
nang o » nang co, nang ho, nang ro
ve cam » ve cham, ve cac, va cam
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: vu sach y nang o hoi. hieu ve cam ((xuc gia) or (luc gia)) thanh ((lap cua) OR (lai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang o hoi. hieu ve cam ((xuc gia) OR (luc gia)) thanh ((lap cua) OR (lai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang o hoi. hieu ve cam ((xuc gia) or (luc gia)) thanh ((lap cua) OR (lai cua)) triet*".
