Confucius advocated "going to Xia Zhishi". According to Confucius' research, the summer calendar is the most reasonable calendar for China as a nation and this land space. Where is rationality? This problem is very deep, and it is necessary to study astronomy and Yin and Yang in the Book of Changes. For example, the gossip in the Book of Changes shows the knowledge of time and space in this world, including astronomy, geography and personnel. A student went to Australia to work and took a China compass with him. When he arrived in Australia, he wrote to ask how to use this China cultural thing in the southern hemisphere. After I thought about it, I told him to use it in reverse. As a result, the letter said that the reverse is very correct. I have never been to the Southern Hemisphere for personal experience. Later, I thought that the earth is round like a watermelon. Although in the Southern Hemisphere, the direction of north and south is the same as that of China, so I wrote to ask him to use it at home. He wrote back that according to the field experience, it was the other way around. At present, this issue is left here for the time being, and no final decision has been made, but my conclusion should be applied in both directions, depending on how it is used. I'll talk about it later when I have a chance to study the Book of Changes. The above mainly shows that our calendar came from Xia Dynasty, from Xia Yu until now. Why is the summer calendar also called the lunar calendar? Because the fifteenth day of each month is based on the day when the moon is round when it comes out of the east, the name of the moon is lunar, so it is called lunar calendar. So our calendar, according to the solar calendar or not? In fact, we are the same, waiting for five days, waiting for three times, and waiting for six days. Twelve months a year, seventy-two days, twenty-four integrity. What crops are planted in the festival is fixed, which is the law of using the solar calendar. The most common folk fortune-telling, geomantic omen, date selection, etc. are also the rules of using the solar calendar. In other words, our history of thousands of years is based on the calendar of Yin and Yang. Therefore, thousands of years ago, our astronomical level has improved very high. But in the past 6 or 7 years, has there been an astronomy department in our university? In the past, there was an astronomy department in CUHK. At present, so many universities do not have an astronomy department, which is very regrettable in terms of education and culture. In the past, there was a Mr. Gao Pingzi who could combine western astronomy with China's astronomy, so I told my students to learn from him quickly, and if they didn't learn from him, they would be extinct. Unfortunately, these students are useless. After studying several times, they didn't have this scientific mind and didn't go on studying. Mr. Gao also passed away a few years ago. I am really worried that China culture will be cut off. Now don't say that there is no astronomy department. With the astronomy department, who can really understand China's own astronomy? China Astronomy has its own system. This is a very sad and pitiful thing to talk about culture. I often say that if the national culture is cut off, it will never turn over.

Until my generation, many people still used the lunar calendar for their birthdays. My parents and grandparents used the Gregorian calendar as my birthday was more meaningful, so I always used the Gregorian calendar as my birthday. I am very unfilial and always forget my parents' birthdays in the lunar calendar. I can't remember the excuse that the lunar calendar changes every year.
The lunar calendar, one of the few traditional cultures that can be passed down, is gradually disappearing from our lives. When I was a child, I had to put on a new thick calendar at home during the Spring Festival. Every day, there was always a bright red lunar calendar date next to the date of the AD calendar, and I also sent some auspicious words such as being suitable for marriage and not moving, which were gaudy and eye-catching.
Later, the small calendar was replaced by the colorful calendars of the big one. The date of the lunar calendar is infinitely reduced and embedded under the number of the western calendar. I can't see clearly with bad eyes, and I'm too lazy to see with good eyes. Later, there was no calendar, and there was everything in the mobile phone, and nothing was left.
when it comes to astronomy, Mr. Wang is so saddened. You know, Mr. Wang talked about this Analects of Confucius in the 197s. Today's society has been predicted by Mr. Wang, and traditional culture can be described as a dead end. Are there any astronomy departments in domestic universities? There are departments of aeronautics, astronautics, physics and biology. I have never heard of such a tall department of astronomy. Anyway, I haven't heard of anyone studying astronomy around me, in my mobile phone or in books. Are those scientists at NASA studying astronomy?
