Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
cham thuc » nham thuc, pham thuc, tham thuc
thanh vi » thanh va, thanh ve, nhanh vi
va triet » va thiet, va trien, ve triet
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
thuc va » thuc vat, thuc dan, thuc day
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: su sach y nang xa hoi. lieu va cham thuc va ((thanh vi) or (hanh vi)) ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. lieu va cham thuc va ((thanh vi) OR (hanh vi)) ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. lieu va cham thuc va ((thanh vi) or (hanh vi)) ((cua triet) OR (va triet))*".
