Everything is silent, except for the legend of the prosperous age of Yongle and the glorious imperial capital. There is a lot of traffic, there is singing and dancing. Zheng He's treasure ship returned from the West for the seventh time, bringing back rare treasures and congratulations from all nations. The "Yongle Dadian" had been completed long ago and was shelved in a high cabinet, becoming a symbol of the empire's civil rule. The project of moving the capital to Beijing is also nearing completion. A more majestic capital will soon replace Jinling and become the center of the empire for hundreds of years to come. Everything seems to be prosperous, the country is peaceful and the people are safe. No one remembers the short-lived Jianwen Dynasty anymore, no one remembers the cruel Jingnan War, and no one remembers the nine young lives who tried to change history but were eventually crushed by history. Their names, their stories, their ideals, their sorrows... Were all completely dissipated in the wind as if they had never existed. Only the cold and majestic Forbidden City, the endlessly flowing canal water, the vast grassland wind and snow, the inaccessible mountains and valleys... Still silently bear witness to the long-gone and unknown blood and tears, loyalty and righteousness, love and hate, ideals and disillusionment. Everything was silent. Underneath the prosperity, there is complete forgetfulness and silent sadness. The nine tripods return to oneness and return to nothingness. The long song should be cried, but no one listens to it.
