Perhaps you should try some spelling variations:
thuat chan » thuat toan, thuat san
cua viet » ca viet, cua vat, cua dieu
ly nang » ky nang, ly hang, ly vang
chan ly » phan ly, khanh ly
truc va » thuc va, thuc vat, trung va
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
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 ly nang x hoi. hieu ((ve cau) or (va cau)) truc va hanh di ((cua viet) OR (hoa viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat chan ly nang x hoi. hieu ((ve cau) OR (va cau)) truc va hanh di ((cua viet) OR (hoa viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat chan ly nang x hoi. hieu ((ve cau) or (va cau)) truc va hanh di ((cua viet) OR (hoa viet))*".
