Perhaps you should try some spelling variations:
tranh luan » trinh luan, trinh luat, doanh luan
tran thanh » ban thanh, van thanh, quan thanh
chau tinh » cuu tinh, ha tinh, cua tinh
tran tuan » tran xuan, tran quang, tran van
cong ban » cong bang, cong san, cong tan
ban than » ban thanh, van thanh, ban hang
than cao » toan cao, thai cao, than cap
ho chau » ha chau, ho chu, o chau

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho chau tinh - thanh ((((tran tuan) OR (tranh luan))) or (tran thanh)) trong cong ban than cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chau tinh - thanh ((((tran tuan) OR (tranh luan))) OR (tran thanh)) trong cong ban than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - thanh ((((tran tuan) OR (tranh luan))) or (tran thanh)) trong cong ban than cao*".
