Now many people have poor handwriting, especially the pupils. The letters they write are not tidy and might be sized or spaced (分隔) incorrectly. The capital letters might be in the wrong places. Spelling problems can always be seen in their writing. Sometimes they themselves can't understand the words they wrote. Some experts think it is not good for the children to learn to write too early.
