ICD originated from the World Child Welfare Conference held in Geneva, Switzerland on 1925. I don't know why I chose June of 1 year as ICD: According to one theory, the Consul General of China in San Francisco Cisco (USA) convened some China orphans to celebrate the Dragon Boat Festival in 1925, which happened to be June of that year and coincided with the meeting in Geneva.
June 1 has since been regarded as ICD； by many countries, especially communist countries; In the western world, ICD is usually celebrated on other days of the year (if any), and the public usually knows little about these celebrations. (For further discussion, see the section on Germany below. )。 Therefore, there is sometimes a misunderstanding that the ICD of June 1 day was invented by communists. Nevertheless, in recent years, even some groups in the United States began to observe ICD on June 65, 438+0.
