The author visited Chengtian Temple at night. Why did he think of going to the temple at night?

The feelings expressed in Night Tour in Chengtian Temple are subtle and complicated, including the sadness of relegation, the feeling of life, the joy of enjoying the moon and the leisure of walking. When the author "undressed and wanted to sleep", he "entered the house by moonlight", so he "set off happily". Moonlight is rare and can't help but make people happy. However, no one enjoyed the moon with him, so he had to go to Zhang Huaimin and he was demoted. How many sorrows and feelings about life have been relegated! Two people strolled in the atrium, which was very leisurely. Compared with "idle people", it contains all the meanings. It vividly depicts the clear and transparent moonlight and reveals the author's special mentality, that is, self-adaptation and self-disdain, although he felt slightly during his relegation. Expressed the author's broad-minded and optimistic mind.
