About cash withdrawal in banks...

Since withdrawing more money from the atm is such a hassle,only 2000 RMB each time and 20000 RMB is the max amount one can withdraw per day(does it means I got to make withdrawal 10 times in order to get this amount?)--my question is--can I go straight to the Bank of China or ICB and use my visa/master cards to make bigger amount of cash withdrawal directly ?thank you
