In May, the weather in Europe was staggering. When we drove from our hotel to Ryusen in the morning, the rainstorm was pouring and water was everywhere. Everyone feels that today's tour is over. Ryusen, the "most Swiss place", has difficulty getting off the bus, let alone enjoying its scenery. Always optimistic lobby also said that the next thing to look at our eight words. Fortunately, the eight characters are good. More than an hour's drive to Ryusen, the heavy rain began to stop, the day was still cloudy, but this has not prevented us from getting off. Because this is the last city to travel through Switzerland, some of the tourists have to buy something, while others can't wait to visit the beautiful lake of Ryusen, the gallery bridge on the lake, the water grille and other scenery. My husband didn't know when he got cold and coughed a lot in the car. The guide suggested that he go to the Swiss pharmacy to buy medicine, saying that Swiss medicine is very effective. We led him to a pharmacy, where the pharmacist asked him about his symptoms and medical history, and then gave him a box of drugs (14 Euros) and ordered him to take one tablet a day. The pharmacy also has products in Chinese characters, which seem to be popular with Chinese tourists. The cough stopped after three days of taking the medicine, and there were no other side effects. It's a very symptomatic treatment. I have to marvel at the effectiveness of Swiss medicine. It's very gratifying to meet such a thing when I go out. Ryusen, Switzerland, has not only beautiful scenery, but also first-class medicine.
