Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
cua triet » cua viet, su triet
va thanh » gia thanh, ban thanh, va tinh
va triet » va thiet, va trien, ve triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
su xac » pu xac, su cac
xac ky » cac ky, sac ky, bac ky
ve cac » vien cac

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: su xac ky lang xa hoi. hieu ((ve cac) OR (va cac)) duc va thanh lap ((cua triet) OR (va triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky lang xa hoi. hieu ((ve cac) or (va cac)) duc va thanh lap ((cua triet) OR (va triet))~".
• Adding a wildcard symbol may retrieve word variants: su xac ky lang xa hoi. hieu ((ve cac) or (va cac)) duc va thanh lap ((cua triet) OR (va triet))*.
