Dear Delegates:

Due to the unexpected COVID-19 positive cases reported in some provinces of the mainland China since last week, the control policy fastened in most provinces, including Guangdong Province, where our conference will be held, we have to make a hard decision that the conference will mainly go virtually. The on-site delegates will not be required to go to Zhuhai, Guangdong for in-person attendance. Instead, we will set up multiple branch conference sites – the main conference site will be in Beijing, and the other branches will be in Shanghai and Guangzhou etc. However, the whole conference program will keep the same instead of going online.

We apologize for any inconvenience to you by this unexpected change. Many thanks for your understanding, and looking forward to seeing you all virtually during the conference.

The Working Committee of the 1st AOC
