Is it more suitable for children to learn soft pen calligraphy or hard pen calligraphy in senior one?

The first-grade children mainly change from kindergarten to primary school, which requires writing. Of course, the correct writing method can help children improve their self-confidence and writing speed. My children began to study after the Spring Festival, in Fang Art School near Overseas Chinese Greenland Avenue. After studying hard pen for several months, I feel that my progress is still obvious.
