Why did Song Zhenzong leave a joke for later generations when he went to Mount Tai to "worship Zen"?

Song Zhenzong's meditation trip to Mount Tai left a joke for later generations. This is because he gave a gift to Wang Dan, the then prime minister, in order to get him to agree to the idea of going to Mount Tai for meditation. It was also because of Song Zhenzong's gift to Wang Dan that Wang Dan personally led officials to invite Song Zhenzong to meditate in Mount Tai. Moreover, Wang Dan even forged a sealed book with others, which met the requirements of the ancient emperor for closed-door Zen.

Moreover, during the period of Song Zhenzong, the time, material resources and manpower he consumed in meditation on Mount Tai were unprecedented. It can be said that when the situation in the Northern Song Dynasty was erratic, he insisted on the meditation of Mount Tai, which undoubtedly brought many disadvantages to the court at that time. When Song Zhenzong thought he was qualified to meditate in Mount Tai, it was also because during his reign, he made the League of Yuan Tan signed by Liao and Song Dynasties, and finally stopped fighting with each other. Because of this, Song Zhenzong felt that he had the capital to meditate in Mount Tai.

In fact, as far as Song Zhenzong is concerned, he is not qualified to meditate on Mount Tai. What he called restoring peace to the situation was achieved only after paying a great price. However, Song Zhenzong's excellence lies in his shamelessness, and others around him advised him to meditate, so Song Zhenzong finally decided to meditate in Mount Tai.

However, he went to Mount Tai to meditate, and finally left an eternal joke. After that, he didn't have the courage to meditate in Mount Tai. It can be said that Song Zhenzong also broke the idea that many emperors meditated.
