Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
va hanh » van hanh, va thanh, va danh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » va cam, ve cai, ve cau
ve cac » va cac, vien cac
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cac))) or (ve cham)) luc va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cac))) OR (ve cham)) luc va hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cac))) or (ve cham)) luc va hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cac))) or (ve cham)) luc va hanh vi cua triet*.
