Perhaps you should try some spelling variations:
trinh luong » trinh duong, trinh huong, trinh xuong
kiem soat » kiem toan
dung lan » dung luan, dung land, dung lam
quan van » quan va, quan luan, quan doan
va kiem » van kien
bien so » bien doi
lan va » luan va, lanh va, lan van
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 lan va kiem soat ) or ( trinh luong ((quan van) OR (luan van)) bien so ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tin dung lan va kiem soat ) OR ( trinh luong ((quan van) OR (luan van)) bien so ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tin dung lan va kiem soat ) or ( trinh luong ((quan van) OR (luan van)) bien so ))*".
