Under the impact of the epidemic, the mobility of people is limited. Bothdomestic and foreign customers are limited by the epidemic prevention policy,so they can't go further to BQC factories and companies for on-the-spotinvestigation. Therefore, we broke through the location restriction, vigorouslycarried out online factory inspection activities, and showed our employees,departments, production lines and equipment to our customers in an all-roundway through sophisticated cameras, and the project leader would explain them inreal time. We hope that our customers will have a clear understanding of BQC,dispel the hesitation and doubt caused by "invisibility", and closethe cooperation relationship.
