Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, truong thanh
tranh chan » tranh chap, tranh cua, trinh chat
chan dang » phan dang, chan dung, nhan dang
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong tan » cong tac, cong san, cong ty
toan cau » 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: "theo chu xanh - canh tranh chan dang ((cong thanh) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - canh tranh chan dang ((cong thanh) OR (cong tan)) toan cau*.
