Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
toc sai » toc san, toc dai, thuoc sai
nang xa » nang x, lang xa, nang ma
sai ky » sac ky
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va cao
va dao » ca dao
vi cau » di cau, viet 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: toc sai ky nang xa hoi. hieu ((ve cau) OR (va cau)) tao ((va dau) OR (va dao)) vi cau treo~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sai ky nang xa hoi. hieu ((ve cau) or (va cau)) tao ((va dau) OR (va dao)) vi cau treo~".
• Adding a wildcard symbol may retrieve word variants: toc sai ky nang xa hoi. hieu ((ve cau) or (va cau)) tao ((va dau) OR (va dao)) vi cau treo*.
