In 2022, there were outbreaks of epidemics all over the country, and the journey on business trips was even more difficult, not only in terms of increased costs compared to normal, but also in terms of time, which was three times that of normal business trips, and sometimes it was hard to get to the construction site to complete the task, and then when we moved to the next construction site we needed to pass through the layers of anti-epidemic barrier, which was accompanied by the risk of being quarantined at any time. Even at such a difficult time, all of our regional after-sales staff did not retreat, still bravely on the road. Unable to reach the site, they contacted the customers through email, mobile phone video and other channels to provide them with one-on-one professional guidance; where they could reach, they ate and lived with the workers in the mines, and from the equipment site inspection to the debugging of the new machine, and then patiently and carefully taught the operators and carefully informed them of the various precautions, our service personnel are all in every detail, and do everything themselves, just to ensure the smooth operation of all the Zico equipment and solve the customer's problems. We are committed to ensuring the smooth operation of all zega equipment and solving customers' worries.
