Perhaps you should try some spelling variations:
vat thanh » dat thanh, gat thanh, tat thanh
thanh vi » hanh vi, thanh va, thanh ve
ky tang » ky nang, ky dang, kho tang
tang ma » mang may, tang van
ve cham » va cham, ve chat, vu cham
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac
vi cua » vai cua, di cua

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 cac ky tang ma hoi. hieu ((ve cham) OR (ve cac)) thuc vat thanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang ma hoi. hieu ((ve cham) or (ve cac)) thuc vat thanh vi cua tre*.
