Which is more suitable for children to practice calligraphy, Tian Zige or Jing?

Tian Zi Plaid is best for children to practice calligraphy! You can buy copybooks with grooves for children to practice online! I think that copybook is more effective and older than ordinary copybooks. After the groove copybook is written, the words will disappear in about five minutes. You can practice it again, which is very convenient and can be used many times!
