If you know PS, you can do it yourself. The making method can be found here:/ss _ kk _ YY/blog/item/E8E5a473428c19fd1435894.html.
If the graphic shop prints A4 on both sides, and the price ranges from 4 to 10 yuan, you can arrange 2 to 3 postcards.
If you have made more than 100 sheets, you can call me. My friend's company has a digital printing machine (commercial industrial printer), which can be customized for you. Thank you!

1. There is a stamp market near Shengli Bridge on a street in Russia, where there are postcards, but not many.
2. Half of the foreign language bookstores near Tianjin Street Book Building belong to the post office, and I also bought some nice postcards. But I don't know what's going on now
