What time is it in the morning?

It should be Chen Shi. It means from seven to nine.

Chen is from 07:00 to 09:00 in the 24-hour system, and Chen refers to the east-southeast in the direction. Chen in the five elements represents earth, and Chen in the theory of Yin and Yang is Yang. In order to facilitate memory, people correspond each earthly branch to each zodiac in sequence, so Chen matches the dragon in the zodiac, while Kang Su (Kang Jinlong) corresponds to 28 huts. The fifth position of the twelve earthly branches belongs to the dragon. At this time, the sun began to dissolve dew, and vegetation began to grow. This is the moment when everything wakes up.

Extended data:

In ancient China, people used the method of "dripping water from a copper pot" to divide a day and night into twelve periods, and each period was called an hour. The first hour of every hour is the beginning, and the last hour is positive.

For example, Chen Chu at 7 o'clock, Chen Zheng at 8 o'clock, Sichuan at 9 o'clock and 10 Sichuan. Twelve o'clock can mean a day or any time. 12 hour is equivalent to 24 hours, and each hour is equivalent to 2 hours.
