Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nam thuc » nam thuoc, am thuc, nam thu
hanh lai » hanh lam, hanh tai, thanh lap
lai cua » dai cua, hai cua, lai chau
va hanh » van hanh, va thanh, va danh
so sach » so sanh, bo sach, co sach
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa

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 xa) OR (lang xa)) hoi. hieu ve ((cam xuc) or (nam thuc)) va hanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y ((nang xa) OR (lang xa)) hoi. hieu ve ((cam xuc) OR (nam thuc)) va hanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y ((nang xa) OR (lang xa)) hoi. hieu ve ((cam xuc) or (nam thuc)) va hanh lai cua triet*".
