Perhaps you should try some spelling variations:
thuong lan » thuong han, thuong mai, tuong lai
phuong lan » phuong la, phuong linh, phuong tran
dung quan » dung quang, dung luan, luong quan
kiem soat » kiem toan
quan van » luan van, quan va, quan luan
van kiem » va kiem, van kien, van hieu
tin » tinh

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tin dung quan van kiem soat ) or ( anh ((thuong lan) OR (phuong lan)) van kiem soat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tin dung quan van kiem soat ) OR ( anh ((thuong lan) OR (phuong lan)) van kiem soat )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tin dung quan van kiem soat ) or ( anh ((thuong lan) OR (phuong lan)) van kiem soat ))".
• Adding a wildcard symbol may retrieve word variants: (( tin dung quan van kiem soat ) or ( anh ((thuong lan) OR (phuong lan)) van kiem soat ))*.
