Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh van » thanh san, thanh toan, thanh phan
thanh va » hanh va, thanh ha, thanh ve
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
cam tu » cam thu, dam tu, tam tu
nam tu » nam thu, nam thuc

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. hieu ve ((cam tu) OR (nam tu)) ban ((thanh va) or (thanh van)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ve ((cam tu) OR (nam tu)) ban ((thanh va) OR (thanh van)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ve ((cam tu) OR (nam tu)) ban ((thanh va) or (thanh van)) cua triet*".
