The level of the old apprentice has taught you enough! ! Unless you are strong, the old apprentice will not teach you at that time, or at least there will be an old apprentice who is stronger than you. Teaching at the first level is also efficient. The old apprentice can guide you hand in hand and know you quite comprehensively. After all, there is only one coach! !

Many martial arts schools are like this, because even if the coach teaches you, he will try his best to give you some advice within the scope of your recent improvement.
