Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
thuc dan » thuc hanh, hoc dan, thuc vat
danh vai » danh sai, danh va, doanh van
dan danh » van danh, han danh, ban danh
su sach » so sach, vu sach
hieu va » lieu va, hieu qua
ly nang » ky nang, ly hang, ly vang
y nang » ky nang, v nang, may nang
co hoi » co hoc, co loi
va am » va lam, va cam

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) or (ly nang)) co hoi. hieu va am thuc dan danh vai ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ly nang)) co hoi. hieu va am thuc dan danh vai ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (ly nang)) co hoi. hieu va am thuc dan danh vai ((cua triet) OR (va triet))*".
