Perhaps you should try some spelling variations:
phan thuong » hang thuong, phan xuong
cong phan » cong nhan, cong khan, chong phap
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
bi tinh » vi tinh
con dan » co dan, con ban, con day
so bi » so di, so li, so ki

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: so bi tinh - thanh cong phan thuong ((con dan) OR (cong dan)) ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so bi tinh - thanh cong phan thuong ((con dan) OR (cong dan)) ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: so bi tinh - thanh cong phan thuong ((con dan) OR (cong dan)) ((toan cau) or (toan cao))*.
