1860, the main force of the Qing government marched south to the Taiping Heavenly Kingdom, and the capital was empty. The British and French allied forces took the opportunity to capture Tanggu, and Emperor Xianfeng fled to chengde mountain resort.
After the British and French allied forces entered the city, they looted Yuanmingyuan, and countless treasures fled overseas. After the looting, the British and French allied forces set fire to the royal garden, which was the first in the world at that time. Like the Nanjing Massacre, Yuanmingyuan is a shame that the Chinese nation can never forget, and it will be beaten if it falls behind.
