According to the "Bengbu City Chronicle", in 1980, the Settsu Economic and Trade Friendship Delegation came to Bengbu for the first time. I visited six times in six years from 1980 to 1985. In 1985, during the celebration of the anniversary of the establishment of sister cities, representatives of the two cities planted cedar trees in the Nanshan Children's Park and erected a monument to commemorate the two cities. The then Bengbu city leader inscribed on the monument "China-Japan Friendship Will Everlasting". According to the person in charge of the Municipal Foreign Affairs Office, Settsu City and Bengbu City established a sister city relationship in May 1984. From 1986 to the present, successive mayors of Settsu, Nobuya Inoue, Kaoru Morikawa, and Kazumasa Moriyama, have led delegations to visit Beng. The many exchanges in culture and education, especially youth calligraphy, have established a friendly tradition of exchanges between the two cities. Shortly after the Bengbu Calligraphers Association was established, Mr. Yamamoto Akira, president of the Settsu City Calligraphers Association, came to Bengbu to communicate with members of the Calligraphers Association. In August 1987, Mr. Akira Yamamoto led a youth calligraphy friendship group to Beng and exhibited 19 works. According to the "Bengbu City Chronicle", at that time, young calligraphy enthusiasts from the No. 3 Middle School in our city held a calligraphy art exchange meeting with Japanese young friends. Calligraphy exchanges have gradually become a tradition and testimony of the friendship between the two cities, and the Settsu Bengbu Japan-China Friendship Youth Calligraphy Exhibition has been held to this day.
