I don't think this is a good way to write it, because anyone with a little business experience knows that the chairman is only for big companies, and it is right for small companies. As long as there is a board of directors, there will be a chairman. It's just that everyone thinks that only big companies can show the identity of the chairman. Small companies will feel a little exaggerated, some will scare people and give people an unrealistic feeling in business dealings.
It is suggested that you don't need such a title, just the general manager.
