The wind comes from the sea and the tide rushes into the Pearl River estuary. The report of the 20th National Congress of the Communist Party of China proposed to promote the construction of the Guangdong Hong Kong Macao Greater Bay Area, support Hong Kong and Macao to better integrate into the overall national development, and play a better role in realizing the great rejuvenation of the Chinese nation. At present, Nansha District of Guangzhou is speeding up the construction of a major cooperation platform between Guangdong, Hong Kong and Macao, and the construction of Dawan District is advancing in depth, presenting a vibrant and prosperous scene. The Pearl River meanders into the South China Sea. Nansha, Guangzhou, is at the intersection of rivers and seas. In June this year, the General Plan for Guangzhou Nansha to Deepen the Comprehensive Cooperation between Guangdong, Hong Kong and Macao Facing the World (hereinafter referred to as the Nansha Plan) issued by the State Council proposed to accelerate the promotion of Guangzhou Nansha to deepen the comprehensive cooperation between Guangdong, Hong Kong and Macao, build a major strategic platform based on the Bay Area, cooperating with Hong Kong and Macao, and facing the world, and better play a leading role in the construction of the Guangdong Hong Kong Macao Greater Bay Area. On September 19, the on-site meeting of Guangdong Province to promote the implementation of the Nansha Plan was held in Nansha. Focusing on further promoting the construction of the Guangdong Hong Kong Macao Greater Bay Area, the study, deployment and implementation of the Nansha Plan, promoting Guangzhou to realize the new vitality of the old city and the "four new and brilliant" were carried out. Guangzhou and Nansha District were required to shoulder the main responsibility and territorial responsibility, and to promote the implementation with the strength of the whole city and the whole district. High quality development: push forward the wave of scientific and technological innovation. Walking along the tree lined streets of Nansha, you can see a car wearing a "hat" from time to time - this is the autonomous vehicle launched by Xiaoma Zhixing - the roof is its sensor and radar, which can detect objects within hundreds of meters of vehicles. In October 2017, Ma Zhixing settled down in Nansha. In just a few years, Xiaoma Zhixing has accumulated more than 13 million kilometers of road test mileage, becoming the first autonomous driving enterprise in China to obtain a taxi business license. "Fast but not broken is an important magic weapon for the development of Xiaoma's wisdom. Nansha's courage to support the new thing of automatic driving was a great help to us." Peng Jun, CEO of Xiaoma Zhixing, said. The rapid development of Xiaoma Zhixing is a vivid footnote to Nansha's promotion of scientific and technological innovation. In recent three years, the average annual growth rate of high-tech SMEs in Nansha District has been 106%, and more than 620 AI and biotechnology enterprises have gathered. In 2021, there will be 11 enterprises in Nansha, including Xiaoma Zhixing, selected into the list of "Unicorn" innovative enterprises in Guangzhou. Nansha's technological innovation tide is surging forward, which also brings more new opportunities for Guangdong Hong Kong Macao technological joint innovation. In Nansha Binhai Park, the sea breeze is blowing and the green shadows are whirling. In the Fok Ying Tung Research Institute of the Hong Kong University of Science and Technology not far away, the 100M network dedicated line extended from the cabinet of the Nansha Branch of the National Supercomputing Center in Guangzhou closely connects the National Supercomputing with Hong Kong's scientific and creative forces. The research team of Professor Zhang Xin from Hong Kong University of Science and Technology carried out research projects such as resistance test for cyclists, helping Hong Kong cyclist Li Huishi win a precious bronze medal at the Olympic Games; Professor Shao Minhua from the Department of Chemistry and Bioengineering of the Hong Kong University of Science and Technology has developed a new type of hydrogen fuel cell, which has set a record in terms of battery durability; The team of Professor Gan Jianping, a Hong Kong physical oceanographer, developed the first interactive ocean simulation system and visualization platform "Wave Ocean" in China
