The monitoring and command center of a mining company in Yulin has purchased a total of 18 55 inch LCD splicing screens, which have been delivered for use recently. The leaders of a mining company in Yulin are very satisfied! Thank you very much for Mr. Wang's trust and support! I am also very grateful to the colleagues in the technical installation department. During the epidemic, not only did I do a good job in epidemic prevention, but I also completed the installation and delivery on time!
