Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh lai » hanh lam, hanh tai, thanh lap
bao thuc » cao thuoc, am thuc, va thuc
cao thuc » cao thuoc, can thuc, cao thu
toc cach » hoc cach, toc sach, truoc cach
nang ma » tang ma, sang ma, nang cao
cach tu » cach thuc
nang xa » nang x, lang xa, mang xa
va hanh » van hanh, va thanh, va danh
lai cua » dai cua, hai cua, lai chau
hieu va » lieu va, hieu qua

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: toc cach tu ((nang xa) OR (nang ma)) hoi. hieu va ((cao thuc) OR (bao thuc)) va hanh lai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc cach tu ((nang xa) OR (nang ma)) hoi. hieu va ((cao thuc) or (bao thuc)) va hanh lai cua triet~".
• Adding a wildcard symbol may retrieve word variants: toc cach tu ((nang xa) OR (nang ma)) hoi. hieu va ((cao thuc) or (bao thuc)) va hanh lai cua triet*.
