Officials' private time

It's unreasonable for the government to curb the private life of government officials in order to improve their work efficiency, says an article in Xi'an Daily. Following is an excerpt:

Leshan, a tourism city in Sichuan province, recently banned government officials from "excessive entertainment out of normal eight-hour workdays" for the reason that their work would be affected adversely the day after.

Superficially speaking, this ban sounds reasonable. According to the physiological wiring of human beings, wild nightlife will result in slow mental responses the following day.
