复旦大学教授王振忠在徽州田野考察时，意外发现一批旧书信，书信距今已近百年，究竟是何人所撰，寄往何处，写给何人，难以一一详考。不过，这批书信墨迹新鲜，保存良好，所述之事，宛如昨日。 《云寄故乡》参展2017年瑞士尼翁国际纪录片电影节。

A young filmmaker returns to China from study abroad, speaking French on the phone. He journeys from Shanghai to a remote monastery . A subtle, intimate and mysterious study in contrasts that touches on family, loss, guilt and creativity. Here is a China in transition, with confusion and alienation along with the steady beat of Buddhist chants.
