Waterloo Bridge, located in London, England, is a stone arch bridge with a long history. When transliteration of its name in Chinese, it is found that there is an allusion between loyal love and blue in China-that is, a wooden suspension bridge in Shaanxi Province is called "Blue Bridge", and its name contains a pronunciation similar to "Soul Broken Blue Bridge", so "Waterloo-Huali-Trudeau" is directly simplified as "lánqiáo-" Blue Bridge.
