Rather than rushing to fill the vacancy, I watched to see which employees would voluntarily pick up the slack.

而不是急于一下子填满所有的空缺职位，我很注意观察，那一位员工能自觉地从松弛状态恢复过来。

Whether sleep on back or on side, it can fill up the space of neck and arms, and slack muscles and keep natural physiological conditions.

无论仰睡或侧睡，均可填补颈、膊空间，松弛肌肉，保持自然生理状态。
