How to treat the behavior of giving people food at a banquet?

When visiting other people's homes, it is a kind of enthusiasm and a local custom for the host to help the guests. There is nothing wrong with guests eating without their own chopsticks. At the banquet, people around you help others with food, usually for the elderly or children, so they can't reach it or feel embarrassed. This is a good habit. They don't patronize their own meals, but also illuminate others. People should do this. I admire such people very much, but they should use clean chopsticks or public chopsticks that no one has used, so that the people who are taken care of will not find it unacceptable, and the delicious food will not be polluted and eat gratefully.
