Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
ve cham » va cham, ve chat, vu cham
vai cua » dai cua, hai cua, lai cua
tuc van » thuc van, truc van, tuc va
su sach » vu sach
nang xa » nang x, lang xa, nang ma
so sach » so sanh, bo sach, co sach
ve cam » ve cac, va cam, ve cai

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