We need to further explore the methods and institutions of democratic oversight, and further expand the scale and channels of forging unity and friendships," said Yu Zhengsheng, chairman of the Chinese People’s Political Consultative Conference (CPPCC) National Committee, when delivering a report on the work of the CPPCC National Committee's Standing Committee in Beijing on Saturday.
