You can start practicing running script from high school. Running script can improve your writing speed and make your handwriting more mature. It is a font between regular script and cursive script, which can be said to be cursive script or cursive script.
cursive script is characterized by simple structure and continuous strokes. It is highly recommended that you practice cursive script. Who can understand it? It should not be used in formal occasions. For example, if you use cursive script in the exam, your score will definitely be particularly low. This is also a respect for others.
there is no need to write official script. Official script originated very early, which is one of the stages of the evolution of characters, and regular script, running script and cursive script are all derived from it. Basically, it evolved from seal script, which mainly changed the round strokes of seal script into square folds, making writing faster, and it was difficult to draw round strokes when writing with paint on wooden slips. You should know something, but you don't need to write in general.
