Therefore, I have the mentality of compensation for holding the first day and night to enjoy it--"the Fading Violin Music",because it can bring me back the loss of life - listen, in the Blue Bird's Timing, I saw a wind formed of a group of fading smoke alone, guidingme as limp as a child in the twists ,wandering on the path in the field; mother's singing of that song still draws my heat and soul ...... ah, a turning around, a thin light smoke hazes the memory of years ago?

于是，我便抱着补偿的心态日夜欣赏那首《淡去的琴声》，因为它可以带我找回失去的生命——听啊，在青鸟的啼鸣中，我看见孤烟消隐成山风，引导我如儿时一样蹒跚在曲折的阡陌小道；母亲唱着的那首歌，还依稀牵着我百转柔肠……啊，怎么一个转身，薄薄的轻雾就朦胧了那份久远？

Actually, the legacy of the fast-fading socialist ideology fading fast even in this last of the People's Paradises is less pervasive in the city than a surviving aura of the frenzied, sophisticated and doomed international society that flourished here between the world wars, when the Anglo-American International Settlement around the Bund, and the nearby French Concession, set the tone and the reputation of Shanghai.

事实上，社会主义意识形态在迅速消逝（即便在这个最后的人民天堂中它也在迅速消逝），在这座城市中，其遗留下来的影响力，不及那种遗留下来的狂热、复杂、注定融于国际社会的氛围。在两次世界大战期间，这种氛围颇为盛行，当时，外滩周围的美欧公共租界以及附近的法租界，定下了这种基调，并成为上海的声誉所在。
