Regarding business card printing, whether XX Group or XX Co., Ltd. is appropriate?

If there is only one company, it is definitely not appropriate to call it a group. If the other party asks what the company structure is, you will be embarrassed.

It is very easy for a company to change its name. As long as the business name is retained, industrial and commercial changes are very convenient.

Moreover, to really grow bigger, it will definitely be more convenient to retain the parent company and establish new subsidiaries to carry out various businesses; or to establish a new company and acquire the original company.
