Traveling abroad should follow local customs. What are the customs and taboos in Sri Lanka?

Custom: Sri Lankans like red, white, yellow and other colors. Sri Lankans like to celebrate the opening ceremony, foundation stone laying and religious ceremony by lighting lamps, and believe that lighting oil lamps symbolizes the prosperity of the cause and the happiness of life. Sri lankans love "orchids" very much, and regard orchids as national flowers and as a symbol of friendship. People often tie orchids into garlands and give them to guests, and then give them a piece of sauce to express their warm welcome. Taboo: 1. Sri Lanka is a Buddhist country, and monks are often encountered on the road. Please ask permission before taking pictures. In Buddhist culture, the head is very sacred, so you can't touch the head of a child casually.
