Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
thanh di » thanh doi, thanh de, thanh do
nang xa » nang x, lang xa, nang ma
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cai, ve cau
va cam » va cham, va cac, va cao
ve cac » va cac, vien cac
di cua » dai cua, doi cua, de 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 cam) OR (va cam))) OR (ve cac)) tu va thanh di 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 (va cam))) or (ve cac)) tu va thanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((((ve cam) OR (va cam))) or (ve cac)) tu va thanh di cua triet*.
