It is permissible for close relatives to hit the south wall, to watch beloved ones take a detour, and to quietly observe friends stepping into deep pits. One of the hardest practices in life is to hold back tears while watching the ones you love go through fire and water. Everyone lives in their own understanding; some mistakes are not necessarily due to ignorance, but may also be destiny. It is better to stop at the point rather than to restrain the urge to advise, because a person's awakening and growth rely 1% on reminders and 99% on repeated trials and tribulations. Opportunities are very important; although the path is broad, it is also difficult. The people you think you have helped may very well be someone you helped avoid an opportunity for good growth. From a long-term perspective, you are not necessarily right. Those things he has not truly understood will be thrown back at him in another form, repeating the same mistakes. If he cannot bear the pain, he will naturally make a change; if he does not change, it indicates he can endure it. You cannot suffer for him. Each of us seems to live in the same world, but we are fundamentally not in the same time and space. The experiences of an observer may not apply to the lives of others. There are many things in a person's life that must be walked alone; some realizations must come with bloodshed. What we can do is to offer healing medicine when he falls and gets bruised, rather than the blade of blame. The only thing we can do is to be willing to let our loved ones suffer. Goodbye.
