After dinner, Wen Chaoshen washed the dishes and then sat in the courtyard. He took out the brush he had bought and placed the slate on the stove to heat it, practicing calligraphy with water.

Due to the high temperature of the slate, the water marks would dry quickly.

Following Cheng Feng's instructions, Wen Chaoshen repeatedly practiced the character '永' (eternity). It was a very tedious process, and after about an hour, his hand felt sore, so he took a break. Finding the regular practice dull, he began to practice writing it in reverse.

Once you start writing any character backward, it completely loses its essence.
