Is it more than three years or more? Is there anything special?

Very advanced. On June 265438+1 October 2 1,1,there was a piece of news about "Luoyang Bridge Restoration", and its shoulder headline read: "More than three years of skilled craftsmen restored scenic spots". The word "more than three years" seems to be a creation with unclear meaning. Usually we only say "more than ten", "more than one hundred" and "more than ten thousand", not three, four or five ... If we put the word "in" before the word "in", "three years" is right. There is a word "San Yu" in the ancient book. There is a phrase "three days" in the preface of the old version of Water Margin, pretending to entrust Shi Naian. Press: "dog days" means "winter people are idle, night people are idle, rainy people are idle"
