Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh tai
vat hanh » vat thanh, van hanh, va hanh
vai cua » dai cua, hai cua, lai cua
ca thuc » can thuc, cay thuc, va thuc
nang ma » sang ma, nang cao, mang may
tang ma » mang may, tang van
qua ca » qua cac, qua cua, qua cai

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (do sanh)) y ((nang ma) OR (tang ma)) hoi. hieu qua ca thuc vat hanh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) OR (do sanh)) y ((nang ma) or (tang ma)) hoi. hieu qua ca thuc vat hanh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) OR (do sanh)) y ((nang ma) or (tang ma)) hoi. hieu qua ca thuc vat hanh vai cua triet*.
