A staged national project
China adopted a three-step human-spaceflight strategy in 1992: demonstrate crewed flight, develop capabilities such as spacewalking and docking, and build a station for longer stays. These steps addressed different problems. A first orbital flight could be a major national achievement without yet providing the capabilities of a station transport.

Yang Liwei and the first flight
Yang Liwei flew Shenzhou 5 in October 2003. The mission examined the spacecraft environment, the astronaut’s condition and coordination among flight systems. His work depended on launch, tracking, medical and recovery teams. A portrait identifies a participant; the flight record establishes what happened in orbit.

Define success before counting firsts
In a fictional readiness review, the launcher works but the team has no demonstrated way to recover the crew. That is a partial result, not a complete human mission. Write down the required chain: reach orbit, sustain the occupants, control the return and recover them. This habit makes comparisons between programs more informative than a ranking of firsts.
