Perhaps you should try some spelling variations:
thuat chan » thuat toan, thuat san
cua triet » cua viet, su triet, va triet
chan ky » chuan ky, than ky, nhan ky
truc va » thuc va, thuc vat, trung va
hanh di » hanh vi, hang di, danh di
hanh de » hanh ve, hanh kem
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va dau
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 chan ky nang x hoi. hieu ((ve cau) or (va cau)) truc va ((hanh di) OR (hanh de)) cua triet~.
• 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 di) OR (hanh de)) 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 di) OR (hanh de)) cua triet*".
