Although it's called Dao Gong, it's not like Jin Yong's magical power has a secret. Since it accounts for Gong Zi, the real secret formula is practice, the industry is good at being diligent and lazy, and the success is destroyed by thinking. The formula is a mental method, which comes from comprehension. You need to sum up your experience through constant practice and failure. Everyone can change tricks, and each family has its own ingenious ways. When I was in Beijing Hotel, the master said that I would have to cut my hand 999 times before I could practice my swordsmanship. At that time, I was frightened. Look at my hand. No matter what the plan is, if I cut my hand 999 times, it will not be minced meat. After decades, I feel that it is not the key to cut my hand several times, but the key is to use my heart. Nothing is difficult in the world, and I am afraid that there is a will.

finally, the formula: mind, mind, spirit and spirit, plus diligent practice, success will come naturally.

good luck.
