How to make your calligraphy more powerful?

First of all, when writing, the wrist is generally in a natural state and the fingers are used flexibly; Second, pay attention to the weight when writing, and don't write too fast, otherwise you will be weak. For example, when writing, don't write too fast, you should write slowly, the end of the pen should be written gradually, and the bending range should not be too large. In fact, you can compare rubbings and find the shortcomings at once! Third, strokes can not be ignored. A well-structured word can only give people a whole beauty, just like a rough-looking beauty. The beauty of strokes is the real beauty, so it is essential to start and close the pen unless you are a master! Hehe, this is just my own little suggestion, for mutual encouragement only!
