Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh va, hanh tai, hanh van
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
thi van » thi lan, thi hanh, thi nang
van cam » van nam, van lam, van cau
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang xa hoi. thi van cam ((xuc va) or (thuc vat)) ((hanh vai) OR (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. thi van cam ((xuc va) OR (thuc vat)) ((hanh vai) OR (hanh vi)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. thi van cam ((xuc va) or (thuc vat)) ((hanh vai) OR (hanh vi)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. thi van cam ((xuc va) or (thuc vat)) ((hanh vai) OR (hanh vi)) cua triet*.
