Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
hanh vai » hanh vi, hanh va, hanh tai
van tham » van thanh, van tuan, van chat
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
co sach » bo sach, cuon sach, hoc sach
vai cua » dai cua, hai cua, lai cua
su sach » so sach, vu sach
tuc va » truc va, tuc xa, duc va

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