What religion does India believe in? What should I pay special attention to when going there? What are the taboos in dress, speech and behavior?

More than 80% of India's population believes in Hinduism, and there are Muslims, Sikhs, Buddhists and Christians in India. Among them, Hindus don't eat beef because cows are regarded as sacred animals. Most people do not use cowhide products. Cowhide products are not allowed to enter temples in India, and you need to walk barefoot. Women should wear appropriate clothes, the top should not be too short, and the lower body should wear trousers or long skirts.
