Usually, the Bao Dao glasses we are talking about are glasses chain enterprises from Taiwan Province Province, which registered the trademark of "Bao Dao". This is a national chain store. Now there are more than 1000 people in Chinese mainland.

Others also have some Bao Dao glasses, such as Hangzhou Bao Dao glasses. The business license name of this enterprise is Hangzhou Bao Dao Glasses Company. There is no registered trademark, it is also a chain, but the scope is smaller, and there are more in Zhejiang Province.

It cannot be simply understood that whoever is older is authentic. One is a trademark and the other is a brand name (business license name) protected by law.

It's like Nike and Artie's stores are all over the street. In fact, their business license is not necessarily called Nike clothing store or Adidas clothing store. As long as you are authorized to use this trademark.

The picture you provided is also from a certain place in Baodao Optical Company (Fujian). There are many authorized chain stores, but the quality is slightly lower than that of Baodao Optical in Taiwan Province Province.

Taiwan Province Baodao Optical Company is neither a Baodao Optical Company nor a Taiwan-funded enterprise in many places, but it is promoting "Baodao Optical Company from Taiwan Province Province".
