Why do people offer Buddha statues and hang crosses? Is it to drive away ghosts and demons?

Offering Buddha statues has two meanings. The first is: repaying kindness. All sentient beings are kind to us. The greatest kindness is that of teachers. Buddhas and Bodhisattvas are our teachers. Only when we accept the teachings of Buddhas and Bodhisattvas can we truly awaken and realize our Dharma body and wisdom. Therefore, making offerings to Buddhas and Bodhisattvas is to commemorate our teachers. We are grateful. forget. The second meaning is the most important: See the wise and think of others. Buddha was cultivated by ordinary people. Offering his image reminds me to learn from him and become a Buddha. We must learn from the Buddha's intentions and aspirations, and learn from the Buddha in everything we do in life, work, dealing with things, treating people, and receiving things. If you cannot treat Buddhas and Bodhisattvas as gods, then you are superstitious and wrong. If you turn Buddhism into a religion, it will not be education.
