过去从未消逝，它甚至从未过去。
The past is never dead; it is not even past.
安全环保是企业的生命线，任何时候都不能放松。
可持续发展不是选择，而是负责任企业的唯一出路。
The biggest risk is not taking any risk. In a world that is changing quickly, the only strategy that is guaranteed to fail is not taking risks.
Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
