Is the rice noodle crossing the bridge self-taught or built with water? I heard from relatives in Yunnan that the rice noodles crossing the bridge actually came from Jianshui, not Mengzi. What happened? It is said that crossing the bridge rice noodles originated in Mengzi, which is just a legend and story, and there is no exact historical record for textual research. However, there are detailed records of the year and missionary place in Jianshui county annals, and the legend of Mengzi is full of loopholes, which only rose in modern times. But I think it doesn't matter where it originated. Jianshui and Mengzi belong to Honghe Hani and Yi Autonomous Prefecture, but 1 more hours away, the customs and dialects are basically the same. Even if Mengzi is not the birthplace, it has played a great role in promoting rice noodles to cross the bridge. Just as table tennis was not invented by China, China can make it into a fine ball and use it as a national ball. Whether Mengzi built water or not, it belongs to Honghe Prefecture.
