Perhaps you should try some spelling variations:
thuat thanh » thuan thanh, thuat than, thuat toan
thanh lay » thanh lap, thanh tay, thanh lam
cua triet » cua viet, su triet, va triet
lay nang » may nang, day nang, ly nang
van hanh » van thanh, ban hanh, van anh
loc van » luoc van, hoc van, lo van
ve cau » ke cau, le cau, ve cai
va cau » van cau, va cac, va dau
ve cac » va cac, vien cac
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat thanh lay nang x hoi. hieu ((((ve cau) OR (va cau))) or (ve cac)) loc van hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat thanh lay nang x hoi. hieu ((((ve cau) OR (va cau))) OR (ve cac)) loc van hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat thanh lay nang x hoi. hieu ((((ve cau) OR (va cau))) or (ve cac)) loc van hanh vi cua triet*".
