Original text: Play a thousand tunes and then the sound will dawn; Watch a thousand swords and then recognize the weapon.

Only you can understand music after practicing a thousand pieces of music, and you can know how to identify swords after observing a thousand swords.

It is not easy to learn a skill in translation; to be a connoisseur, you also need to observe more objects, and talking on paper will not work. You need to read thousands of volumes before you can write with divine help. If you do anything without a certain amount of experience, you will not have high attainments.

These two sentences of truth are of great guiding significance for us to improve our literary accomplishment, improve our appreciation of various arts, and identify the level and depth of skills.

If you want to comprehensively observe and analyze something, you must first be knowledgeable. That is to say, the improvement of various skills mainly depends on your own practice. At the same time, you must observe more and appreciate the practice of others. For example, when it comes to boxing, people talk about it and practice it every day, but in fact they are not willing to endure hardships and stand hard work, let alone humbly ask for advice, or they only try it superficially, do not know it deeply, and learn only superficially, but in the end they will not be able to get in. Suppose you have practiced boxing yourself and are willing to endure hardships, but if you just practice behind closed doors and are unwilling to observe other people's practices, then you will be looking at the sky from a well, and at best you can maintain your original level. Because when you look at Mount Tai, you can see the world is small; when you look at the sea, you know how small the ravines are; without comparison, you can't know good or bad; without comparison, you can't see the difference. Why is boxing not the same? You can't improve yourself without looking at others, let alone carry forward your inventions and creations. Therefore, Liu Xie proposed to have a "wide view".

Field practice is the practice of learning, and erudition is the practice of appreciation and comparison. Combining the two, only by being knowledgeable can you enrich your own shortcomings, increase your understanding of your own level and the profundity of other people's skills, and then you can Only by carving out your own path and measuring the gap between yourself and others can you have the initiative in analyzing and commenting, and can you understand the essence without being blinded by certain phenomena. Although you can achieve results by practicing hard on your own, in the final analysis it has its limitations. A weak vision means a weak mind, so observing others is very helpful to yourself. I hope that during the learning process, every opportunity to observe and learn will be cherished.
