Is Oupai Wooden Door a listed company? How long has it been established?

Yes, it was established in 2006, and was listed on the A-share of the main board of Shanghai Stock Exchange on February 17. I think it is still very good, and it is worthy of recognition in that respect. Oupai takes "global wooden door manufacturing expert" as its own responsibility. Since its establishment, it has focused on wooden doors and devoted itself to innovation, and established "Wooden Door R&D Center" and "Wooden Door R&D Center".
