Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
nhanh lang » nhanh quang, nhanh thang, nhan dang
hanh mang » nhanh mang, hanh trang, thanh hang
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, cong tan, huong dan
toan ban » van ban
toan cao » toan tap

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 - ((hanh mang) OR (nhanh lang)) va nhung cong dan ((toan ban) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh mang) OR (nhanh lang)) va nhung cong dan ((toan ban) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh mang) OR (nhanh lang)) va nhung cong dan ((toan ban) or (toan cao))*.
