Perhaps you should try some spelling variations:
thuat chan » thuat toan, thuat san
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
chan ky » chuan ky, than ky, nhan ky
va hanh » van hanh, va danh, ban hanh
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va dau
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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: thuat chan ky nang x hoi. hieu ((ve cau) OR (va cau)) truc ((va hanh) OR (va thanh)) di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat chan ky nang x hoi. hieu ((ve cau) or (va cau)) truc ((va hanh) OR (va thanh)) di cua triet~".
• Adding a wildcard symbol may retrieve word variants: thuat chan ky nang x hoi. hieu ((ve cau) or (va cau)) truc ((va hanh) OR (va thanh)) di cua triet*.
