Perhaps you should try some spelling variations:
cau tren » cu tren, dau tren, ca tren
nang ma » tang ma, sang ma, nang cao
ve cham » va cham, vu cham, ve chim
ve chat » va chat, van chat
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
tu cao » cu cao, tu cac, vu cao
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac
vi cau » va cau, ve cau, di cau

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 cao ky nang ma hoi. hieu ((((ve cham) OR (ve chat))) OR (ve cac)) thuc va hanh vi cau tren~.
• Adding a wildcard symbol may retrieve word variants: tu cao ky nang ma hoi. hieu ((((ve cham) or (ve chat))) or (ve cac)) thuc va hanh vi cau tren*.
