Geographical location introduction: The Catholic Church is located on a high slope in the middle of Zhejiang Road, so it is particularly conspicuous. As long as ships on long voyages see it, they will know that they have arrived in Qingdao. The road up the street is paved with bluestone slabs. Walking on it, along with the dessert shops, Western restaurants and small shops on the roadside, you suddenly feel like you are in a leisurely town on the European coast. It is intoxicating.
