Perhaps you should try some spelling variations:
dung tren » dung trong, dung trung
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
duc van » duc tan, duc manh, duc phan
anh tai » hanh tai, anh thai, vanh tai
cuu tre » cua tre, cau tren, cau treo
su sai » su tai, su hai, su dai
sai ky » sac ky
ve cam » ve cham, ve cac, 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: su sai ky nang xa hoi. hieu ve cam ((duc van) OR (duc va)) anh tai ((dung tren) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang xa hoi. hieu ve cam ((duc van) OR (duc va)) anh tai ((dung tren) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: su sai ky nang xa hoi. hieu ve cam ((duc van) OR (duc va)) anh tai ((dung tren) or (cuu tre))*.
