When Emperor Taizong of Tang once asked Yuan Tiangang a question when he returned home from his resignation, he asked him: When did the Tang Dynasty fall? We all know that in the past five thousand years of Chinese history, the change of dynasties has followed an inevitable law, that is, "long-term integration will be united, and long-term integration will be divided." Despite this, each emperor did not accept his fate and tried to make his dynasty eternal.
In ancient times, witchcraft was very popular, like the Qin Dynasty, the Han Dynasty, etc., were very obsessed with this oriental magic, and then made themselves eternal youth, immortality. So today, Xiaobian tells you about an emperor, who is equally famous with the Qin Emperor Han Wu and created the "Rule of Zhenguan" Tang Taizong. For us modern people, he is an emperor who can be described as a wise king. Internally, he worked hard to govern, so that the society at that time was once peaceful and peaceful, and the people's lives were extremely happy, and he killed decisively, and successively conquered the Turks, XueYantuo and other places. His series of deeds were enough for many emperors to learn from and learn from.
But after all, he is a mortal after all, and naturally understands a truth: prosperity will decline. In order to solve the problem that had plagued him for a long time, he asked Yuan Tiangang a question that concerned the lives of his entire family: "How old do you think this emperor can live?" This question is not easy to answer, once the emperor is not satisfied in the slightest, Yuan Tiangang's little life can be a life whine! So how did Yuan Tiangang answer? Yuan Tiangang was known as the "Master of Xiangxue" at that time, his position at that time was to manage astronomy, and his head was naturally bright, he replied: "Long live Your Majesty, long live, long live!" This slap on the back of the horse's ass made Tang Taizong unable to say anything, and Yuan Tiangang escaped punishment.
Yuan Tiangang's greatest contribution was "Pushing Back Map", which was a masterpiece he co-authored with Li Chunfeng, comparable to "Qimen Dunjia". Although Yuan Tiangang held a high official position, he did not like this kind of life, which was plagued by the mundane objects of the court every day. Therefore, he proposed to Tang Taizong that he wanted to resign and go home, but Tang Taizong agreed but asked Yuan Tiangang to finally count him before leaving. Yuan Tiangang naturally responded, at which time Tang Taizong asked, "How long can my Tang Dynasty operate?" Another proposition was thrown to Yuan Tiangang, who replied, "When a pig can go up a tree," meaning that the Tang Dynasty will live forever, and Tang Taizong is satisfied and smiling. However, some descendants said that "pig" had a homophone "Zhu", and indeed later there was a Liangwu Emperor surnamed Zhu who destroyed the Tang Dynasty. If Tang Taizong could understand it at that time, wouldn't the result be different? History has passed, and naturally none of us knows it
