Perhaps you should try some spelling variations:
kho tang » cao tang
cai kho » dai kho, chai khoa, tai khoa
tang ma » mang may, tang van
hieu va » lieu va, hieu qua
thuc va » thuc dan, thuc day
cua tre » cua te, cuu tre, cua triet
tu cai » tu cac, tu can, tu bai
ma hoi » mai hoi, xa hoi, ma hoa
vi cua » vai cua, di cua
va am » va lam, va cam

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 kho tang ma hoi. hieu va am ((thuc va) OR (thuc vat)) hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cai kho tang ma hoi. hieu va am ((thuc va) or (thuc vat)) hanh vi cua tre*.
