The "Doudou OK" and "Dou Dou OK" apps all use the membership mode. After downloading the app, you must enjoy the activation process to use the mobile device to query the virtual account information and materials at any time and place. Of course! You can get more "Golden Beans" through the App! These virtual “Golden Beans” in the App can be exchanged for catering, poker games and surrounding products in the “Cooperative Store” provided in the App (the details should be based on the on-site announcements of each partner)! Let us experience the convenience of "Doudou OK" and "Dou Dou OK" together!
