You can go to Taiyang Bridge and see the building materials market. My friend bought the Probach brand from Dr. Lock Smart Lock Store, which is pretty good. Moreover, they have many famous brand fingerprint locks with many styles. Many people in Evergrande use their products.
I hope it helps you, remember to adopt it! ! !
