Just in time for the Mid-Autumn Festival in Cologne, I saw that the Chinese people next to the church organized a lot of celebrations to promote Chinese culture. The more you are in a foreign country, the more united you have. Speaking of the church, it goes without saying that it has a long history and has been renovated many times in a long time. Speaking of climbing the steps to the top of the church, the observation deck is still relatively open, but unfortunately for protection, it is difficult to see the transparent scenery through the grid. The church tour index in Cologne is definitely five stars. The interior design of the church, the light transmission layout is perfect, and the mastery of the architectural craftsmanship of the predecessors is marveled.
