Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
su triet » su viet, su tien, ve triet
va triet » va thiet, va trien, ve triet
xuc gia » duc gia, luc gia, tuc gia
te sach » toc sach
sach ky » sac ky, sach y, sach ty
van cau » van hau, van chat, toan cau
van dau » van dao, phan dau
nang o » nang co, nang ho, nang ro
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: te sach ky nang o hoi. hieu ((van cau) OR (van dau)) xuc gia thanh vai ((va triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang o hoi. hieu ((van cau) OR (van dau)) xuc gia thanh vai ((va triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang o hoi. hieu ((van cau) OR (van dau)) xuc gia thanh vai ((va triet) or (su triet))*".
