For instance, the technicians responsible for equipment installation.
In a work cycle, only the initial period requires equipment installation; once the equipment is installed, maintenance only occurs if there's a problem, and there's nothing else to do.
The equipment transported to the moon is of very high quality, and it's very unlikely that any major issues will occur, so the technicians related to the equipment enjoy a lot of downtime.
Some of these individuals are Yixing Company employees, while others work for the Aerospace Bureau; they also participate in other tasks during their spare time.
Another direct example is Li Renzhe, whose work on the moon involves research on Mutated Red Spirulina. Unlike coding, bacteriological research requires constant vigilance, but his workload is even more relaxed than on Earth; he might only need to spend two hours in the lab per day, with occasional inspections being sufficient.
