Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
van khang » van khanh, van quang, van hanh
van thanh » ban thanh, van tuan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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 trinh ((van khang) OR (van thanh)) cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh trinh ((van khang) OR (van thanh)) cong tan ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh trinh ((van khang) OR (van thanh)) cong tan ((toan cau) or (toan tap))*.
