In terms of discipline or singing performance:

When you see people being kind, you think of others; when you see people being evil, you think introspectively. If there are any, please correct them, and if not, add a warning.

Don’t cross the threshold, don’t limp, don’t lean on the skipper, don’t shake your knees

Unintentional is not called wrong, intentional is not called evil

Excesses can be changed to nothing if covered up. Yigu

When performing and singing:

Step calmly, stand upright, bow deeply and bow respectfully

When encountering difficulties in learning to sing: do not be afraid of difficulties and do not take them lightly

Only learning with morals and talents is not as good as self-study

You can also quote when practicing music and self-study:

Be broad within limits and be tight and work hard until you are stagnant
