珍惜每一滴水，这种观念正在深入人心。２００２年，我在太原工作的儿子家过元宵节，意外地发现了一种令人欣喜的现象。他们在家里搞起了节水，而且收到了十分明显的效果。我原来是搞水利工作的，尤其对节水情有独钟，所以在欣喜之余总想把他们的节水办法宣传出去，供大家参考 Cherish every drop of water, this concept is deeply rooted. In 2002, my son who worked in Taiyuan had a Lantern Festival and unexpectedly found a delightful phenomenon. They did a good job of saving water at home and received very clear results. I was originally engaged in water conservancy work, especially in favor of water-saving, so I am always happy to save their water out of publicity, for your reference
