It is the first time that I know Sun Moon Lake from the textbooks of primary school. I have a lingering plot in my heart. So I decided to go to Sun Moon Lake even if the time is tight. We rented two mountain bikes and started a happy and romantic tour around the lake. The water in Riyuetan Lake is very clear, changing with the sky, blue and green; the trees along the bank are very beautiful, dancing with the wind, or green or green, colorful. It's really intoxicating! Renting bicycles: NT$100 per day, very cheap. Luggage Deposit Skills: There is a coin-operated luggage locker at Taichung-Ukraine-Japan High-speed Railway Station, next to Starbucks in the station. Large, medium and small cabinets are priced at NT$50, NT$40 and NT$30 every 3 hours, which is very economical.
