Perhaps you should try some spelling variations:
cham thuc » nham thuc, pham thuc, tham thuc
qua cham » qua hai, qua cac, va cham
thuc va » thuc vat, thuc dan, thuc day
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
luu tre » luu tru, cuu tre, luy tre
su xac » pu xac
su cac » tu cac, su cao, su can
me hoi » le hoi
vi luu » vi lua

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: ((su xac) OR (su cac)) ky nang ((me hoi) OR (xa hoi)). hieu qua cham thuc va danh vi luu tre~.
• Adding a wildcard symbol may retrieve word variants: ((su xac) or (su cac)) ky nang ((me hoi) or (xa hoi)). hieu qua cham thuc va danh vi luu tre*.
