Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
vi hoa » voi hoa, va hoa, bi hoa
vi hoc » li hoc, va hoc

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: tu sac ky nang xa hoi. hieu ve cham ((xuc van) OR (duc van)) thanh ((vi hoa) OR (vi hoc)) viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cham ((xuc van) or (duc van)) thanh ((vi hoa) OR (vi hoc)) viet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cham ((xuc van) or (duc van)) thanh ((vi hoa) OR (vi hoc)) viet*.
