A Chinese Biographical Dictionary/Chang Shao
101 Chang Shao 張邵 (T. 元伯) A man of the Han dynasty, famous for his friendship with one 范式 Fan Shih. On one occasion, they arranged to meet again on a certain day, after an interval of two years; and Chang insisted on his mother cooking a fowl in readiness for his friend, who arrived at the appointed time. When Chang died, he appeared in a dream to Fan, who at once set off to be present at his obsequies. The funeral, however, had already been planned to take place before his arrival; but when the procession came to start, it was found that the coffin was immovable. And so it remained, until Fan rode up on a white horse, dressed in mourning clothes.
