Perhaps you should try some spelling variations:
minh tuong » minh tuan, minh quang
tuong quan » truong quan, thong quan, luong quan
minh cuong » dinh cuong, manh cuong, minh vuong
cuong quan » luong quan, vuong quan, luong quang
hieu hoat » hieu hoa, thien hoat, hieu suat
hieu luat » hieu qua
kiem soat » kiem toan
quan van » luan van, quan luan, quan doan
van kiem » va kiem, van kien, van hieu
quan va » quan vi, quan ha, luan va

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"minh tuong quan va ((hieu hoat) OR (hieu luat))\\") or (\\"minh cuong quan van kiem soat\\"))\"".
• Removing quotes may allow a broader search: (( minh tuong quan va ((hieu hoat) OR (hieu luat)) ) or ( minh cuong quan van kiem soat )).
