《论衡·卷二十四·难岁篇》
丑在子的东边，亥在子的西边，丑、亥之地的人家向东西方搬迁，触犯了太岁所在的位置；巳、未之地的人家向东西方搬迁，触犯了太岁所冲的方位。
丑在子东，亥在子西，丑、亥之民东西徙，触岁之位；巳、未之民东西徙，忌岁所破。
Ugly is on the east of Zi, and Hai is on the west of Zi. People at the place of Ugly and Hai move to the east or west, which offends the position of Taisui; people at the place of Si and Wei move to the east or west, which offends the direction that Taisui dashes to.
