Core setting: The protagonist Lin Qing is an invisible rich man born in Chaoshan, Guangdong. He has an extraordinary taste (golden tongue) and can accurately taste the origin of ingredients, cooking techniques, secret seasoning recipes, and even taste the humanistic stories behind the food. Tired of the delicacies of the mountains and seas in commercial entertainment, he took his exclusive photographer A Zhe, starting from Guangdong, and traveled to 34 provincial-level administrative regions across the country in a counter-clockwise route. He checked in 20 authentic delicacies in each province. He did not accept advertisements or carry goods. He simply shared the true taste of food through short videos and live broadcasts, and used his camera to record the customs and craftsmanship behind the food. He has gained numerous followers and became a national-level food blogger.
