Perhaps you should try some spelling variations:
thien van » thi van
va triet » va thiet, va trien, ve triet
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
cau luc » cau truc, cau phuc
su sach » so sach, vu sach
mai hoi » mai khoi, dai hoi, lai hoi
van cau » van dau, van hau, van chat
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
ma hoi » xa hoi, ma hoa, me hoi

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 y nang ((ma hoi) or (mai hoi)). thien van cau luc va ((thanh vi) OR (thanh ve)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ((ma hoi) OR (mai hoi)). thien van cau luc va ((thanh vi) OR (thanh ve)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ((ma hoi) or (mai hoi)). thien van cau luc va ((thanh vi) OR (thanh ve)) va triet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang ((ma hoi) or (mai hoi)). thien van cau luc va ((thanh vi) OR (thanh ve)) va triet*.
