193 1 year, Japan launched a war of aggression against China. Before long, all three northeastern provinces fell and became Japanese colonies. After the Japanese occupied the northeast, they thought the name was unreasonable, so they established the puppet Manchukuo. And asked Puyi to be the head of the puppet Manchukuo, and later became Emperor Kant. Japan has coveted the Northeast since ancient times, and it is impossible to give real power to a China person. So this positioning made by Puyi is just a hollow name, but when Puyi left the Forbidden City in Beijing, she took something with her. After all, Puyi is the emperor, and there are many jewels and cultural relics around him. At that time, Puyi carried a lot of cultural relics with him during the transformation. In the early stage of the Reform Movement of 1898, Puyi seemed obedient, but in fact he secretly instilled the history of Manchu in prisoners. Because there was no hope of recovery, people around Puyi betrayed him one by one, and even his nephew threatened him to report his possession of jewelry to his superiors. In desperation, Puyi had to hand it over to the state. Tian Huangshi three-chain seal consists of three seals, all of which are Tian Huangshi, which are connected into a whole by three Tian Huangshi chains and become inseparable parts of each other. This is an object left by Qianlong, with an ellipse on both sides, a yin and a yang on the side, "Dry Chris Lung" in the yang text and "Excellent only" in the yin text; The oval seal means "Lotte". Among the many famous Tian Huangshi products collected by Emperor Qianlong, the most famous one is Tian Huangsan, which is connected by three Tian Huangshi chains, except for the nine-reading nine-piece set famous for its huge lineup. This treasure is a rare treasure. When Puyi donated this treasure to the Palace Museum, it became the treasure of the town hall of the Palace Museum.
