I went to Bao Tu Quan too, the spring are really clean and many people around the spring and try to feel it, and i was trying to do that too, but i almost fell into the spring when my friend didn't hold me well, kinda scary, but that day was really hot, i wish i can jump into the spring and swimming inside, i am just thinking i know that`s impossible.
And i have to mention the willows on the side with the budding green leaves which make you feel how great the Spring is, no wonder it`s the best season to come here and walk around. Terrific!
