1. 相：即随旺气而生，例如春令为木旺，木能生火，火自然也就旺起来，这便叫做相。
E. g. Wood is Wang in spring, and wood can produce Fire (from 5 elements productive/growth cycle), hence Fire is Xiang.
2. 休：即旺气已经过去，例如水旺於冬，到了春天则水之旺气已过，转入休息之期了，所以叫做休。
E. g. Water is peak during winter, but in spring it is away from peak, moving into rest state, hence it is called Xiu.
