May 1, International Labor Day, a holiday belonging to all workers.

Salute them for their hard work, crossing 5 continents and 3 oceans to perform overseas installation tasks. To them for keeping up with their studies and constantly refining their professional abilities. To them for carefully attributing the cause of the trouble, locating and solving the trouble like a cocoon. To their continuous efforts. To each and every one of our workers who keep the spirit of rigour and mastery in their field. Let the sound of each drop of sweat fall into the thunderous applause of the workers!
