In Yongfuli, Shanghai in the late 1980s, Lin Wan, a girl in a pavilion, and Gu Huai'an, a young man who has returned from abroad, were heart-beating while singing softly on a semiconductor radio. The great waves of the times are surging - the alleys are being demolished, the wild geese are disconnected, the tide is rising in the sea, and they are far apart. In the new year of the millennium, we meet again in Shanghai, and the heart-stirring imprint of the past has not faded. After going through career ups and downs and the epidemic of the century, the young love that had been locked away for half a lifetime by a plaid handkerchief finally found its home under the new holly tree by the Suzhou River. We are rooted here and breathe together with this city - this is the most reassuring answer after thirty-six years of dust.
