Can anyone attend Sotheby's Shanghai preview?

You can't. Sotheby's Shanghai preview needs to be registered as a member of Sotheby's auction to participate. Not everyone can participate. Sotheby's 2023 Hong Kong Spring Auction China Mainland Tour Shanghai Preview was held at MGM Hotel on the west coast of Shanghai, with nearly 150 collections covering China artworks, China paintings and calligraphy, and China ancient paintings and calligraphy.
