Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh lap » thanh san, phan lap, thanh hai
va thanh » gia thanh, ban thanh, va tinh
lap cua » lai cua, tap cua, lam cua
hoa hoi » khoa hoi, hoa hoc, hoa doi
xac ky » cac ky, sac ky, bac ky
ve cac » vien cac
ha hoi » ha noi, xa hoi, va hoi
su xac » pu xac, su cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang ((ha hoi) OR (hoa hoi)). hieu ((ve cac) or (va cac)) duc va thanh lap cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang ((ha hoi) OR (hoa hoi)). hieu ((ve cac) OR (va cac)) duc va thanh lap cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang ((ha hoi) OR (hoa hoi)). hieu ((ve cac) or (va cac)) duc va thanh lap cua triet*".
