Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau
ve cac » va cac, vien cac
tu gia » tu giao, tu giac, tu giay
va cua » va chua, via cua, ma cua
ca cua » co 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 ((ve cai) OR (ve cac)) tu gia thanh ((va cua) OR (ca cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((ve cai) or (ve cac)) tu gia thanh ((va cua) OR (ca cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((ve cai) or (ve cac)) tu gia thanh ((va cua) OR (ca cua)) triet*.
