Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
cam duc » cam xuc, cao duc, pham duc
va hanh » van hanh, va thanh, va danh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
vi cau » di cau, viet cau
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va dau

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. lieu va cam duc va hanh ((((vi cau) OR (ve cau))) OR (va cau)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. lieu va cam duc va hanh ((((vi cau) OR (ve cau))) or (va cau)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. lieu va cam duc va hanh ((((vi cau) OR (ve cau))) or (va cau)) triet*.
