Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
doan tien » doan thien, doanh tien, doan dien
tranh he » trinh he, tranh ha, tinh he
he nhung » hee nhung, ve nhung, me nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((doan tien) OR (toan tien)) thanh - canh tranh he nhung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((doan tien) OR (toan tien)) thanh - canh tranh he nhung cong dan toan cao*.
