The night tour of Sanjiang (also known as Three Rivers, constituted by Minjiang, Qingyi and Dadu rivers) has brought about a new format of Leshan night sightseeing. It will also become a new business card for Leshan tourism, continuously driving night tour programs. Following the project of Hangzhou G20, Huairou Belt and Road Forum, Gulangyu BRICS Summit, this project is another successful attempt of Leyard to boost cities’ nighttime tourism economy. In the future, Leyard will continue to build smart city night scenes as the entry point, use the “light + culture + finance” model to spur smart lighting innovation, and vitalize cities’ nighttime tourism economy.
