"If you want to stand up, you must stand up to others; if you want to reach yourself, you must reach others" means that you have to stand firm and let others stand firm, and you want to be prosperous and let others be prosperous.
If you want to establish yourself, you can establish others; if you want to achieve yourself, you can reach others. This comes from "The Analects of Confucius·Yongye" "If you want to establish yourself, you can establish others; if you want to achieve yourself, you can reach others" is a concrete embodiment of Confucianism's "benevolence". A benevolent person is a person who takes "giving alms to others" as his own responsibility, and is a person who is willing to give to others, but the premise is that he must first have strength. If you can't stand firm yourself, how can you help others up?

Practical significance
For more than two thousand years, benevolence, righteousness, propriety, wisdom and trust have been the indispensable moral principles for Chinese people , the most important word "benevolence" embodies the ambition of our Chinese people to take the world as their own responsibility. Each of us should become stronger, not only because being strong can protect ourselves, but more importantly, being strong can better help others.
The motherland has prospered and the country is peaceful and the people are safe, but the strength of the motherland is not only to protect itself, but also to realize the great rejuvenation of the Chinese nation at an early date and better maintain world peace. We should always remember: if we want to establish ourselves, we must establish others; if we want to achieve ourselves, we must achieve others. If you want to stand firm, you must also let others stand firm. If you want to be prosperous, you must also let others be prosperous.
