What did Fahai say about Xu Xian's tonsure?

Fahai told Xu Xian that the Leifeng Pagoda was within a hundred paces, and people who had not become monks could not go in. Xu Xian went up the mountain into the temple and shaved his head voluntarily, just because Fahai said that the Leifeng Tower was within a hundred paces, and he was not allowed to enter until he became a monk. Fahai staggered to his feet and took three steps back. When he turned around, his hair and beard were white. Xu Xian cleans the tower every day, one inside and the other outside.
