The 70th birthday of the XCMG Hoisting Machinery Business Unit. To welcome the "518" 70th anniversary celebration, these days the employees of the Hoisting Machinery Business Unit are always busy during their breaks—some sawing wooden boards, some welding brackets, some painting... busily and joyfully. What they are doing is a big undertaking—"DIY the Most Beautiful Crane in My Heart"—to present a special birthday gift to the company. At the event, 12 exquisitely crafted crane models from different eras stood proud, as laughter and words of praise filled the air.
