Perhaps you should try some spelling variations:
nhanh thang » nhanh thanh, nhanh quang, hanh trang
nhanh lang » nhanh quang, nhan dang, nhanh dong
thong cong » trong cong, tong cong, thong thong
cua thong » cua thuong, cua khong, cua tong
nhung cau » chung cu, nhung bai, nhu cau
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
hang cau » hang dau, hang ca, nang cao

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: theo chu xanh - ((nhanh lang) OR (nhanh thang)) cua thong cong trinh ((hang cau) OR (nhung cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((nhanh lang) OR (nhanh thang)) cua thong cong trinh ((hang cau) or (nhung cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((nhanh lang) OR (nhanh thang)) cua thong cong trinh ((hang cau) or (nhung cau))*.
