Perhaps you should try some spelling variations:
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
van dam » van dao, van dau, van lam
luc cam » luc lam, luc tam, xuc cam
va chua » vua chua, ca chua, va chu
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
va cua » via cua, 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 dang xa hoi. hieu ((van dam) OR (van nam)) luc cam nang ((va cua) OR (va chua)) tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky dang xa hoi. hieu ((van dam) or (van nam)) luc cam nang ((va cua) OR (va chua)) tu~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky dang xa hoi. hieu ((van dam) or (van nam)) luc cam nang ((va cua) OR (va chua)) tu*.
