Duke Zhou cracked the query and dreamed that there was a strange thing on his right eye at night.

Five senses correspond to five elements, and five elements correspond to five internal organs! The liver began to understand, and a strange thing grew in the right eye in the dream.

White is a reminder of blunt and sharp injuries, black doesn't matter, cyan doesn't matter!
