The problem of passing values from parent components after Cascader encapsulation of antd components

is encapsulated using the cascader component (official example: https://ant.design/components...), which is used to select region data.
the data source in this component is dynamic. Now, if you want to transfer the city ID to the child component through the parent component, and the child component loads the corresponding city area according to the city ID, can you provide some ideas for passing values?
regardless of the parent component, the dynamic data is queried and passed to the child component through ref.

Is the

child component loaded so that the city filter is satisfied according to the city passed by the parent component?
