The child has a lot of homework and scrawled handwriting. He has been studying in a calligraphy class for a year, but what if he still can't write at ordinary times?
The main reason is that children have not learned to use the writing methods learned in calligraphy class, but they have not used them at ordinary times. First of all, they may not use them. For example, the calligraphy they learned in China is definitely not a writing brush. Second, they are in a hurry. Now they may learn regular script because they have too much homework and have no time to write this kind of thing slowly according to the method they have learned. They have to wait for regular script to learn running script step by step, so they must be guided to use running script skills when writing at ordinary times.
