PBOC Drains Cash as Overnight Rate Slides to Lowest in past 10 months

The entire article is talking about China and how their central banking system has drained cash from their main system of finances. In my opinion on this article I do not see why they need to continue on draining the banks for their money because they would also be taking the citizens money as well. For the business this hurts them because they are losing money. For the government this is really helping them because they continue get money from the national bank and use it for their own use and how they see fit .
