"Five Lakes and Four Seas" literally refers to China's five major lakes (usually Dongting Lake, Poyang Lake, Taihu Lake, Chaohu Lake, and Hongze Lake) and four major sea areas (the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea), and broadly refers to all parts of the country or the world. Its deeper meaning is to describe people from different places and different backgrounds gathering together, emphasizing the breadth and diversity of regions. This idiom is often used to describe scenes of unity and convergence, such as "friends from all over the world gather joyfully together." In terms of cultural background, it reflects the concept of great unity and inclusiveness in Chinese culture. It originates from The Analects, Yan Yuan: "Within the four seas, all men are brothers," and later evolved into "five lakes and four seas." Its emotional tone is neutral with a positive leaning, often carrying a sense of warmth, boldness, or grandeur. It is used in a wide range of scenarios, such as welcoming guests, describing team composition, and expressing broad unity.
