Perhaps you should try some spelling variations:
cua triet » su triet, va triet
nam thuc » nam thuoc, am thuc, nam thu
hanh lai » hanh lam, hanh tai, thanh lap
cua viet » ca viet, hoa viet, cua vat
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y nang xa hoi. hieu ve ((cam xuc) or (nam thuc)) va hanh lai ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. hieu ve ((cam xuc) OR (nam thuc)) va hanh lai ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. hieu ve ((cam xuc) or (nam thuc)) va hanh lai ((cua triet) OR (cua viet))*".
