"People from the three countries have deep affection for the bird, which has become a symbol of friendship," said Chen Jing, president of the Shanghai People's Association for Friendship with Foreign Countries, one of the organizers of the event.

"Since 1985, these birds from China have been settling down in Japan and South Korea. This has not only created conditions for the protection and rebuilding of the bird community in the two countries, but also created the opportunity to build a new bridge to promote ecological civilization construction based on the cooperation of the three countries," said Chen.
