Beijing-Tianjin-Hebei, the Yangtze River Delta and the Guangdong-Hong Kong-Macao Greater Bay Area are the three major metropolitan areas of China's economic layout, radiating and driving the development of the northern, central and southern regions. President Xi Jinping visited Xiongan New Area last week, accompanied by three members of the Standing Committee of the Political Bureau, who proposed to make the Beijing-Tianjin-Hebei region a pioneer and demonstration area for Chinese-style modernization. With similar positioning, only Shenzhen is a pioneer demonstration zone for socialism with Chinese characteristics and Shanghai Pudong is a leading zone for socialist modernization. This means that Beijing, Tianjin and Hebei will set up different reform pilots and have a variety of national-level policy dividends. This "thousand-year plan" has once again become the focus of attention.
