The system has made me more organized

Meng Kaifeng, 36, a judge at Beijing Haidian District People's Court.

I am responsible for ensuring that the rulings the court makes are implemented. For example, I contact people to verify that they have received compensation and keep in touch with banks to confirm that a debtor has sufficient funds to repay debts. That means a lot of people know my cellphone number.

Before our court established a system on WeChat last year, I fielded about 80 calls a day. If 10 minutes passed without my phone ringing I began to wonder if it was faulty.
