一年一度，周而复始，年年此时，岁岁不同。全球劳动者的创造和奉献，使我们这个世界在不断推向美好、强盛与繁荣。当和平与绿色环保日益成为人们关注的热点和呼声时，历史的责任便成为当代人不可推卸的义务。人们需要安定的生存环境，子孙后代更不希望留给他们千疮百孔的破烂 Once a year, time and again, at this time of year, it is different. The creation and dedication of the global laborers have made our world a better place for prosperity, prosperity and prosperity. When peace and environmental protection have increasingly become the focus and voice of people’s attention, the responsibility of history has become an irresistible obligation for the contemporary people. People need a stable living environment, and future generations do not want to leave them with tears.
