The Daqing Post Office in Zhujiajiao is the most well-preserved site of the Qing Dynasty Post Office in Shanghai, with a long history and humanistic atmosphere. The Daqing Post Office is located in a small alley, and it passed by without paying attention, but the red brick European-style small building shows her uniqueness. According to the tour guide, the post box retained at the door is still the old thing of the Qing Dynasty, and a heavy sense of history suddenly came.
