Perhaps you should try some spelling variations:
day thanh » dao thanh, dat thanh, da thanh
thuc day » thuc dan, thuc vat
thanh ve » hanh ve, thanh va, thanh vien
sang ma » tang ma, nang ma, sang tao
ky sang » ky nang, ky dang, ky tang
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
tu cai » tu cac, tu can, tu cay
tu bai » tu ban, tu bat, te bai
ma hoi » mai hoi, xa hoi, ma hoa
ve cua » le cua, de cua, te cua
ve am » va am

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: ((tu cai) OR (tu bai)) ky sang ma hoi. hieu ve am thuc day thanh ve cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((tu cai) or (tu bai)) ky sang ma hoi. hieu ve am thuc day thanh ve cua tre*.
