What should I pay attention to when traveling to Taiwan alone during the summer vacation?

Taiwan has a tropical climate, with long summers and short winters. May to June is the rainy season, and there are many showers in summer, so it is better to bring an umbrella when traveling. The clothing should be light, but air-conditioning is widely available. If you are going to Alishan and Taitung during the trip, the temperature in Alishan is relatively low, so please prepare a jacket. There are hot springs in Taitung, so please bring your own swimsuit.
