Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
phap sinh » phau sinh, phai sinh, phap tinh
hanh hinh » hanh chinh, hanh tinh, hanh dinh
tong cong » trong cong, cong cong, dung cong
thanh cau » thanh chau, nhanh cau, thanh ca
thanh mau » hanh mau, thanh san, thanh hai
hinh cua » chinh cua, sinh cua, tinh cua
he phap » che phap, de phap, ve phap

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: he phap sinh - hanh hinh cua ((nhung cong) OR (tong cong)) van ((thanh cau) OR (thanh mau))~.
• Adding a wildcard symbol may retrieve word variants: he phap sinh - hanh hinh cua ((nhung cong) or (tong cong)) van ((thanh cau) or (thanh mau))*.
