Who wrote the words on the Shanhaiguan tablet?

Shanhaiguan is an ancient architectural complex, which consists of seven castles, ten passes and countless enemy platforms and piers on the Great Wall. The whole Guancheng has a rigorous structure and clear functions.

The eastern starting point of the Great Wall in Ming Dynasty, the old dragon head, faces the sea, the blue sea and sands, the sky is high and the sea is wide, and the majestic customs are towering. Known as "the throat of the capital, the left throat of Liao". The Great Wall of Jiao Shan, which is connected with Guancheng, is winding, with steep spires and picturesque scenery. The arched tower on the east side of Shanhaiguan City stands high above the Great Wall, guarding the whole city like a mighty and unyielding warrior.

There is a 5.9-meter-long and 1.6-meter-wide plaque on this watchtower, which is engraved with the five characters "the first pass in the world". These five Chinese characters are vigorous and simple, with the meaning of dominating the world and the honor of covering the eight barren areas with art. Who wrote this rare calligraphy in the world? Some people say that these five Chinese characters were written by Wang Xizhi, a calligrapher in Jin Dynasty, while others say that they were written by Yan Song, a traitor in Ming Dynasty. In fact, neither of these statements is correct.

Wang Xizhi was a calligrapher in the Jin Dynasty. Shanhaiguan was built in the Hongwu period of the Ming Dynasty, with a difference of more than 900 years. Yan Song was born in the middle of Ming Dynasty. When he was in power, the first pass in the world had been built 100 years ago. At this time, the plaque of "the first pass in the world" has been hung for many years. It was actually Xiao Xian, a native of Shanhaiguan, one of the 34 calligraphers in the Ming Dynasty, who wrote the plaque "The First Pass in the World".
