Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
danh dai » danh dau, danh di, danh sai
va danh » va dinh, va dan, va hanh
te sach » toc sach
hieu cu » hieu cua, hieu ca, hieu su
y nang » ky nang, ly nang, v nang
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 y nang o hoi. hieu cu ((nhan luc) or (nang luc)) va danh dai ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang o hoi. hieu cu ((nhan luc) OR (nang luc)) va danh dai ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang o hoi. hieu cu ((nhan luc) or (nang luc)) va danh dai ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang o hoi. hieu cu ((nhan luc) or (nang luc)) va danh dai ((cua triet) OR (va triet))*.
