I don't think what you are trying to do is supported by FastAPI (see #3163).

Try:

@app.get("/test")
async def read_query_check(name: Annotated[str, Query(title="名字", description="名字")] = "test"):
    ...

Since FastAPI 0.115.0 you can make it working this way:

async def read_query_check(data: NameSchemas = Query()):
