Did China really go into space? When Shenzhou 5 went into space, was Yang Liwei really the only one in the cabin?

Shenzhou 5 spacecraft is a 1 manned spacecraft developed on the basis of unmanned spacecraft in China, carrying 1 astronaut and running in orbit 1 day. During the whole flight, we will provide the astronauts with necessary living and working conditions, and send the astronauts' physiological data and TV images to the ground to ensure the astronauts' safe return.
