Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
nganh luat » hanh luat
hieu lang » chieu sang, hieu quang, nhieu tang
trung cap » truong cao
nhung cau » chung cu, nhung bai, nhu cau
cong ban » cong bang, cong san, cong tan
ho hieu » ho chieu, hoi hieu, nho hieu

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: ho hieu lang - thanh ((trung cap) OR (trung tam)) nhung cong ban ((nganh luat) OR (nhung cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - thanh ((trung cap) OR (trung tam)) nhung cong ban ((nganh luat) or (nhung cau))~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - thanh ((trung cap) OR (trung tam)) nhung cong ban ((nganh luat) or (nhung cau))*.
