Perhaps you should try some spelling variations:
dung tren » dung trong, dung trung
cuu tre » cua tre, cau tren, cau treo
duc van » duc va, duc tan, duc manh
anh tai » hanh tai, anh thai, vanh tai
van anh » van thanh, tuan anh, van minh
cac duc » cac du, cao duc, cac dac
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
su dai » sau dai, si dai, su tai
su hai » su tai

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 hai) OR (su dai)) ky nang xa hoi. hieu ve cac duc van anh tai ((dung tren) OR (cuu tre))~.
• Adding a wildcard symbol may retrieve word variants: ((su hai) or (su dai)) ky nang xa hoi. hieu ve cac duc van anh tai ((dung tren) or (cuu tre))*.
