I have been practicing running script for more than a year. To have some experience. I specialize in cursive calligraphy by Li Fangming, who has a very domineering and powerful writing style. I'll start with basic strokes. Accompany the head with the radical. After practice. Start tracing. Trace the words repeatedly. I found out that the only way to write good running script is to have perseverance. It really takes several years to practice calligraphy.
