Introduction to Sun Stone: In 1979, the famous singer Zheng Xulan’s song "Sun Island" made Sun Island famous at home and abroad. During the third phase of the comprehensive renovation project of Sun Island, the Harbin Federation of Literary and Art Circles organized many literary artists to search for a boulder that would be integrated with Sun Island, and finally selected today's "Sun Stone". The "Sun Island" on the stone was designed by the famous calligrapher Zhao Puchu In 1984, he inscribed the three words "Sun Island" on the masthead of Harbin Daily's Sun Island literary supplement.
