How did Puyi transport 70 or 80 boxes of paintings and calligraphy to Tianjin?

Although the rare treasures that Puyi and Pu Jie stole from the Forbidden City in Beijing were stored in Qinchun Palace for a period of time, fortunately, they were all moved to the safe place of Tianjin Japanese Concession, which was enough to ensure the prosperity of his life. Regarding the incident, we still listen to the memory of the party Pu Jia: "When these antiques were shipped to Tianjin, they experienced some twists and turns. These books, calligraphy and paintings are packed in 70 or 80 wooden cases, which are large and numerous. Not only do you have to pay taxes when entering and leaving the railway station, but you are most afraid of being inspected. At that time, Sun Baoqi, the national tax supervisor, was the father-in-law of Zailun (the younger brother of the Qing Prince Zaizhen). I went to Zhalun, saying that Qin Chun Wang Fu and our family's things were to be shipped to Tianjin, and asked him to entrust Sun Baoqi with a visa-free and tax-free passport. Sure enough, the passport was successfully completed, and I escorted the antiquities to Tianjin, and all of them were stored in Gordon Road 166 Building. With these rare treasures as a solid capital for Puyi's future life and study abroad, I think living in Tianjin is the most suitable and can be said to be fearless. " During his three months in the Japanese legation, Puyi was taken good care of by his Japanese master, and his "ambition and hatred ... grew day and night. I don't think it's good to stay like this. I should prepare for my future. " 1925 On February 23rd, Puyi quietly boarded a third-class personnel carrier from Qianmen Station in Beijing, accompanied by the secretary of the Japanese legation, Guan Ikebu and others. Puyi took off her glasses that she never took off easily, and put on her hat again and again. At every stop of this carriage, several Japanese plainclothes policemen in blue will come up. When they arrived in Tianjin, almost all the carriages were people dressed in blue. When leaving the station, Puyi was wrapped up by them. In this way, Puyi came to Tianjin under the special protection of the Japanese.
