Montreux, Switzerland, is the seat of Siyong Castle and the birthplace of Swiss rock music. Last year, we stayed here for two days to watch the morning light and sunset of Lake Geneva and enjoy the tranquility and comfort of the small town. Today, in Montreux, where the epidemic prevention period was not over, the streets are not over, Lake Geneva and the small town appear more calm and dignified, and supermarkets and fitness venues are so quiet.
