How many songs does the resident singer sing in an hour?The number of songs a resident singer had to perform varied due to various factors. Generally speaking, a two-hour stand-in singer would have to sing about five to six songs. Based on this calculation, a stand-in singer would have to sing about two to three songs in an hour. However, if it was a two-hour stand-in singer that included the speaking time, about 14 to 15 songs would be enough. This meant that they would have to sing about seven to eight songs per hour. However, in order to ensure a smooth performance, it was recommended to rehearse about 20 songs, which meant that about 10 songs might be sung every hour. At the same time, there were also cases where they could sing 40 songs in a row in a night, and the average could reach 20 songs per hour, but this was a special case. In addition, the number of songs prepared by the resident singers should be at least 30 - 50 in order to cope with the needs of different occasions and atmosphere. This meant that the actual number of performances would fluctuate greatly due to many factors.

English 12-hour to 24-hourHere is how to convert the 12-hour English format to the 24-hour format:
- If the time was 12:00 AM (midnight), it would be 00:00 when converted to the 24-hour clock.
- If the time was between 1: 00AM and 11: 00AM, the 12-hour system and the 24-hour system were the same. For example, 1: 00AM was 01:00, and 11: 00AM was 11:00.
- If the time was 12:00 PM (noon), it would be 12:00 in the 24-hour clock.
- If the time was between 1:00 PM and 11:00 PM, the conversion to the 24-hour system would require 12 to be added to the original number of hours. For example, 1:00 PM was 13:00, and 11:00 PM was 23:00.
In programming, for example, using the Simple Dateformat class of Java, if the format time is in the 12-hour format, use "hh:mm:ss", and in the 24-hour format, use "HH:mm:ss". You can obtain the 12-hour format time and convert it to the 24-hour format according to the above rules.

Using the most common pop music format, MP3, as an example, a one-minute track would require about 10-20MB of data. If you played 10 songs online, then an hour of music playing time might require 100-200MB of data.
However, if the mobile data plan contained more data or the geographical location had better network signal, the data cost might be lower. In addition, you can also consider using some music player software or online platforms that consume less data to save on data costs.
The data cost of an hour of listening to music online on a mobile phone could be between 1GB and 10GB, depending on many factors.

24-hour clockThe 24-hour system was a time recording system that divided a day from midnight to midnight into 24 hours, from 0 to 23 (24 was the midnight at the end of the day). It originated in ancient Egypt, where the Egyptians divided time into 12 hours during the day and 12 hours at night (or 10 hours between sunrise and sunset, 1 hour each at dawn and dusk, and 12 hours at night). At that time, people realized that the length of an hour changed with the seasons. In the 24-hour format, the time is written in the format of "hours: minutes"(for example, 01:23) or "hours: minutes: seconds"(01:23:45), with zeros in front of numbers less than 10 (although it is not necessary in the hour part, it is widely used in computer applications such as the 8601 standard). In an environment where the precision was higher than seconds, the seconds could be expressed in decimals. A day starts at midnight (12:00 or 24:00), and the last minute of each day starts at 23:59 and ends at 24:00. 24:00 on a certain day is equivalent to 00:00 on the next day, and the digital clock displays from 00:00 to 23:59. The establishment of this epoch system benefited from the process of global integration, and it expanded around the world along with the expansion of capitalists. It provided a reference for global synchronization activities and had an important impact on the global economy, politics, and culture.

Is it a day or an hour?The god of value could be related to the day or the hour. From the point of view of the day, there was a god on duty every 360 days a year to monitor the affairs of ghosts and gods in the human world, just like a god on duty every day. There were also different gods on duty every day of the year, and the good or bad luck of the day was determined by the interaction of the gods on duty. From the point of view of the hour, different hours also had different good or bad luck judgments related to the value of the gods. For example, on February 19, 2021, different hours had different good or bad luck judgments. The good or bad luck between 23:00 and 1:00 was the heavenly prison (bad), and the bad luck between 1:00 and 3:00 was the Xuanwu (bad).
