What is the process of calligrapher Wu Changshuo completing a work?

Wu Changshuo himself is not tall and has a plump face. Even though he is over 70 years old, he still looks like a man in his forties and fifties, which is the result of his hard work. Wu Changshuo gets up early every day. After washing, he will think quietly at his desk for 15 minutes and arrange what to do on this day. Wu Changshuo likes to arrange every day in an orderly way and do things according to the arranged process. He just eats breakfast after meditation, but sometimes when inspiration comes, he goes straight to work and even forgets to eat. Before painting, Wu Changshuo always thinks about his ideas first, and it often takes a long time between them. When he is brewing to a certain extent, the whole painting will be done in one go and look effortless. Every painting by Wu Changshuo will be consulted, and corresponding thinking and modification will be made according to their opinions. This shows that even though Wu Changshuo's position is already very high, he will not show off his position, but will listen to everyone's opinions and listen with an open mind.
