When writing in big letters of more than three inches, you should stand up and write cantilever, so that you can work hard and take care of the overall situation. When standing, you should keep your feet steady, with your right foot slightly stepped out, slightly in a T-step, your right half slightly stretched forward, your waist slightly leaned forward, and your left hand pressed the paper or spread it backwards.

Predecessors advocated concentrating the strength of the lower body on the waist, pushing the shoulders with the strength of the waist, driving the upper limbs with the strength of the shoulders, and sending the strength to the pen tip through the upper limbs and wrists, that is, the so-called "strength comes from the waist and roots in the feet". This can be achieved step by step in practice.
