Everyone has a different imagination for the castle. It is a beautiful tall building. It is a luxurious and luxurious lifestyle. Is it a wonderful fairy tale that a beautiful princess, a handsome prince and a chic knight perform together? No matter what, the castle, for us, is always a charming place full of infinite charm with mystery. When we were young, we liked to use sand to shape their vagaries. When we grew up, we saw more and more, and the castle gradually faded away from mystery. If there is still an impulse to the castle, I am afraid that it will only be explored in the sky. In the early morning, the sun was still torn with the horizon, and the mist after the ebb tide covered the earth. In the vagueness, the city of the sky in that dream was really in sight.
