Perhaps you should try some spelling variations:
ky tang » ky dang, kho tang, ky trong
hieu ve » hieu va, hieu van
cac tuc » cac toc, cac tu, cac tac
tuc may » truc may, tu may, tuc xay
via cua » gia cua, gian cua, giau cua
vu sac » vu sach, vu san, va sac
ve cac » va cac, vien cac
va cua » va chua, ca cua, ma 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: vu sac ((ky tang) OR (ky nang)) xa hoi. hieu ve cac tuc may tinh ((va cua) OR (via cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: vu sac ((ky tang) or (ky nang)) xa hoi. hieu ve cac tuc may tinh ((va cua) or (via cua)) tre*.
