Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, dieu vu
hieu su » hieu sau, tieu su, hieu so
soc van » hoc van, oc van, sac van
van anh » van thanh, tuan anh, van minh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cua » de cua, te cua, ve cum
le cua » ly 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: tu sac ky nang xa hoi. ((hieu vu) OR (hieu su)) cham soc van anh ((ve cua) OR (le cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. ((hieu vu) or (hieu su)) cham soc van anh ((ve cua) OR (le cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((hieu vu) or (hieu su)) cham soc van anh ((ve cua) OR (le cua)) triet*.
