The Richest Man in the Song Dynasty

Su Xiaocai returned to the mysterious old rural house and found that there was a secret door in the basement. After opening it, he walked into endless darkness. He could not light a fire or turn on the light, and gradually lost consciousness... When he woke up, he was floating on the water. A group of people stood on a tall wooden arch bridge and were trying to salvage him! The wooden arch bridge is like a rainbow, wooden merchant ships are coming and going, trackers are pulling the boats, shouting low trumpets, and on the river bank, there are people riding donkeys, walking, riding donkey carts, and shouting vendors... Why does this place look so familiar? Su Xiaocai thought for a long time, isn't this a painting? Have you traveled through "Along the River During Qingming Festival"? Since I can walk under the bridge, I wonder if I can walk back through? Su Xiaocai was thinking about it when he was taken away by two street patrolmen...
