There is an inscription on the plaque "The sky is ringing". The first paragraph reads "Twenty-eight years of Emperor Kangxi of Qing Dynasty, the auspicious day in Ji Chun has passed", and the next paragraph reads "The governor of Henan and other places prefects military affairs and manages Yan Xingbang, the right deputy capital of Henan Douchayuan". In the fifteenth year of Chongzhen in Ming Dynasty (1642), Kaifeng was completely submerged by the Yellow River, and the Drum Tower was completely destroyed, leaving only the old site. In the 28th year of Qing Emperor Kangxi (1689), Yan Xingbang, the governor of Henan Province, organized reconstruction. The inscription on the plaque can only explain the reconstruction, but it can never explain that "Loud and Loud" is a strict book.
Because the plaque was not written by anyone, it naturally led to many legends. According to the logic of ordinary people, these legends are mostly around non-celebrities, because people guess that if they are written by celebrities, they will naturally fall on celebrities. In the early years, it was said that these four amazing characters were written by a prison official, who died of illness after doing his best. In the 1930s, there was a new legend. It is said that during the reign of Herry Liu in Henan, his secretary wrote a good hand and was imprisoned for taking drugs. The secretary knew that the master was fishing for fame and asked to talk to him alone. The secretary said: I can write the word "ringing in the sky" better than the four words on the drum tower, so I will sign it in the name of the chairman. By default, Herry Liu sent someone to replace the original plaque behind the secretary's book late at night. Later, the secretary was ashamed of her poor handwriting and changed the original plaque. In the 1950s, when Mr. Li Cunren wrote Kaifeng Places of Interest, he said that these four words were written by Meng Ding, a scholar in Qixian County. In the early 1980s, according to the famous calligrapher Mr. Jin Xuan, these words were said to have been written by his ancestor Jin Biaobiao. According to Mr. Kong, these four words were written by Yuan Shunyi, a Yi nationality, during his trip to Kaifeng, Henan. He once saw this plaque and said it was recorded in the county annals.
There have been different opinions about the origin and destination of the giant plaque above the original drum tower, which has become an "unsolved case". It was not until recent years that there was an answer. It is said that as early as the early 1930s, when the Drum Tower was renovated, the plaque "Sound in the sky" was removed. Its majestic words and beautiful structure always amazed scholars and made Kaifeng people proud. At that time, many people were watching and admiring. Someone invited the Central Plains Photo Studio in Beishudian Street to take a photo, and two days later, the plaque was put back on the Drum Tower. Later, the Drum Tower and the plaque were destroyed by the war, and the only remaining negatives were kept in Mr. Hao's home. Mr. mugwort has kept it carefully for many years. Whenever friends who like calligraphy come to play at home, they just show them the negatives and never develop them. Now, the only negative has been donated by Mr. Artemisia argyi to Hanyuan, China. Mr. Gong Tao personally designated it to be developed, enlarged and carved into a monument, which stood in Hanyuan, China, and made the "sound resound through the sky" reappear.
