Where is there a place or factory in Dalian where you can add environmental protection watermark printing to clothes?

On the second floor of the big food market, there is a middle staircase. As soon as you go up, you will see many shops selling small white shirts. The third floor seems to be in the same position. But I remember a good one, which seems to be on the side of the third floor (on the side of the light rail station). There are couples' shirts hanging in front of his house, clothes printed with some Chinese characters and so on.
