Convergence is often used for things, while convergence is often used for people.

The traditional Chinese character for "Hui" is originally "_", which is a phonetic character with Cong'an and Huai sounds. It originally refers to an ancient artifact. This kind of utensil was probably used to "gather" items. Later, "_" often referred to the intersection of rivers. And further extended to refer to aggregation, synthesis, etc. Perhaps because it is often used to refer to "the meeting of rivers", later the three points of water in "_" were moved outside "博" and written as "_", and "water" became the symbol of this character. Simplified Chinese characters were promulgated and implemented, and "_" was simplified into "Hui", which is also a pictophonetic character, from the sound of "水" or "厚".

The traditional Chinese character for "会" is "_", which looks like a food container with a lid, referring to the lid. The extended term refers to the meanings of gathering, rendezvous, collection, conformity, gathering, etc. It is further extended to refer to the encounter, meeting, gathering, alliance, etc. between people. Later, groups or organizations established by people for certain purposes were also called "hui", such as trade unions, farmers' associations, societies, etc.

Both "hui" and "hui" mean "gathering". Since "hui" is commonly used when people meet, meet, and gather with others, there is a tendency in specific applications: "hui" is often used when used for "people", and "hui" is used for "things". Such as "people soon gathered in the square from all directions", "countless creeks converged into a big river" and so on.
