The host, senior diplomat Zhong Liang, was alone, ordered to come to the Pacific Ocean to represent the small tropical island country Yoshido to build the embassy in Yoshido on his own. Yoshido was a small island country. The environment was closed, there were few people, and the people were rough. Zhong Liang's work in Jido was faced with heavy pressure, danger, and huge loneliness. He condensed the sense of responsibility, honor, and noble sentiments of a diplomat. Bungee jumping was an annual traditional gathering on Yoshido Island, and young men were all enthusiastically participating. Bungee jumping was a metaphor, showing the ups and downs of diplomatic work and dangers.
