In recent years, the emergence of red chips is mainly formed by some mainland provinces and cities reorganizing their window companies in Hong Kong and listing them in Hong Kong, such as "Shanghai Industry". In fact, if you know what red chips are, you will find that although they are all distinguished by color, there is no necessary connection between them.
