First, the general teacher will not let Lanting Preface "Lanting Preface" be written well. It is Wang Xizhi's masterpiece, and the strokes in it have become very numerous. Moreover, this is a work written by Wang Xizhi after drinking, which conforms to his most authentic technique. We beginners can't learn this kind, which is accumulated by Wang Xizhi after years of precipitation. The brushwork here is very complicated. A word can be written in 12 ways. We ordinary beginners may be able to distinguish one from another, so it is difficult to grasp the writing of this copybook. Teachers generally don't advise us to do this at the beginning stage.
Second, the teacher asked us to practice, probably to improve our skills, just like playing the piano. A teacher gave him the most difficult tune, and he practiced it thoroughly, and then he could play it well even if he gave him a simple tune casually. The teacher asked us to practice the Preface to the Lanting Pavilion, and also let us write other simple copybooks easily. Reaching a higher level first and practicing the preface of Lanting well show that we have mastered the essence of calligraphy and can write well.
Each teacher's learning style is different, and his thinking may be different, which is related to their understanding of calligraphy. Some teachers think that beginners should not touch things that are too difficult, but should start with simple things, which creates a problem. It is difficult for beginners to reach the peak of calligraphy. There are also some teachers who ask us to read some difficult things. If we can master them, we can reach a peak of calligraphy, which is the greatest advantage and constantly improve our ability.
