Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
thuc dan » thuc hanh, hoc dan, thuc vat
tuc ban » thuc ban, truc ban, tu ban
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve cam » ve cham, ve cac, va cam
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: ((so sanh) OR (do sanh)) ky nang xa hoi. hieu ve cam ((tuc ban) or (thuc dan)) thanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (do sanh)) ky nang xa hoi. hieu ve cam ((tuc ban) OR (thuc dan)) thanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) OR (do sanh)) ky nang xa hoi. hieu ve cam ((tuc ban) or (thuc dan)) thanh vi cua triet*".
