Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh lai » hanh lam, hanh tai, thanh lap
lai cua » dai cua, hai cua, lai chau
xa hanh » xa thanh, xa khanh, va hanh
cam tuc » cam xuc, nam thuc, dam thuc
hieu ve » hieu va, hieu van
so sach » so sanh, bo sach, co sach
sang ma » tang ma, sang tao, mang may
nang ma » tang ma, nang cao, mang may
cam tu » cam thu, nam tu, dam tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y ((nang ma) or (sang ma)) hoi. hieu ve ((cam tuc) OR (cam tu)) xa hanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y ((nang ma) OR (sang ma)) hoi. hieu ve ((cam tuc) OR (cam tu)) xa hanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y ((nang ma) or (sang ma)) hoi. hieu ve ((cam tuc) OR (cam tu)) xa hanh lai cua triet*".
