1one night in April, 962, Sun Guofan, a treasure thief, first hid in an alley behind the toilet outside the gate of the Treasure Hall. When it was dark and nobody was there, he pushed the scaffold under the wall of the treasure house and turned it into a treasure house. After breaking the window glass, he took out the golden plates and bowls. Then, he pried open a showcase, put two big gold seals in his backpack and went back the same way. At this moment, the Forbidden City has been blocked, and more than 200 policemen and armed police are waiting for him to climb out of the high wall. Sun Guofan thought people didn't know. As a matter of fact, as soon as he entered hall of mental cultivation, the alarm reported the news to the duty room of the Forbidden City Security Office.
