Considering the current situation of COVID-19, to provide a safe and comfortable academic exchange environment for all participants, the conference committee has decided to Change AIAAT 2020 from onsite to Online Meeting. 鉴于当前全球新冠肺炎疫情最新动态，配合做好疫情防控工作，有效减少人员聚集，阻断疫情传播，给所有与会者提供安全的学术交流环境，更好地保障大家的健康安全。经组委会商定，原定2020年8月7 日至9日在中国深圳举行的第四届人工智能应用和技术国际会议(AIAAT 2020)现调整为网络在线视频。
The gleaming manifestation of China's economic miracle, Shenzhen (深圳, Shēnzhèn) has risen from the marshy Pearl River Delta into one of the world's most mega megacities in less time than it took London's St Paul's Cathedral to be built. Millions of migrants have been drawn to its golden gates from the Chinese countryside since the 1980s; now Shenzhen attracts high-flying tech graduates and global corporations. On the map, Shenzhen might look like it's an extension of Hong Kong, but it's firmly in China territory. In terms of logistics, that means most travelers (including US citizens) need a Chinese visa to visit. The city's imposing urban sprawl and cloud-piercing towers can make it an overwhelming destination at first. But the 1,965-foot-high Ping An International Financial Center -- the fourth-tallest building in the world -- provides a helpful landmark, marking the city's Futian central business district. To the west, there's a cluster of theme parks and museums. To the east, you'll find glossy malls, art villages and even some beaches along Mirs Bay.
