Is a one-year life maintenance center reliable? When did it open?

In my impression, I started my business in early 20 17. It seems to be the first medical institution in Lecheng. It has been more than six years this year, and its scale has expanded several times compared with when it first opened. Many people go there for maintenance every year. A while ago, it seemed that their company was still celebrating the anniversary of 19. Very lively and old, I feel very reliable.
