Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van chat » cao chat
van hanh » van thanh, ban hanh, van anh
ve chat » va chat
nang xa » nang x, lang xa, nang ma
sai ky » sac ky
ca dan » cac dan, ca dao
vi cua » vai cua, di cua
tu sai » tu bai, tu san, tu cai

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 sai ky nang xa hoi. hieu ((ve chat) OR (van chat)) luc ((van hanh) OR (ca dan)) vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. hieu ((ve chat) OR (van chat)) luc ((van hanh) or (ca dan)) vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu ((ve chat) OR (van chat)) luc ((van hanh) or (ca dan)) vi cua triet*.
