I've seen the day and night of Xishuangbanna.

The day is like an oil painting, with the blue sky and white clouds within reach, the green Lancang River flowing slowly outside the window, and the breeze is not dry. Walking by the river, this moment is empty. Occasional showers hit the banana trees, adding a bit of romance. The night is Blue Hours, the endless deep blue tone holds me like a dream. Lying by the blue pool, the sky is dotted with stars, quiet and lazy.
