The Tianjin Post Museum, located on the Financial Street of Jiefangbei Road, was the first post office of the Qing Dynasty. It contains the first set of stamps of China, such as the Dragon Stamp of the Qing Dynasty, Ferrar's Manuscripts, and the small red print, which is one yuan. It's a pity that I went there twice. Because of the time problem, I can only leave a little regret to go next time! __________
