Hehe, my friend, what's so strange about this? China is the largest labor market in the world. Sony, ASUS, Acer, ThinkPad, Lenovo, Dell and Hewlett-Packard all have foundries in China (concentrated in the Yangtze River Delta region, and the largest is Shanghai Quanta Kunshan Compal Wistron. . . . ) What you used today, maybe the HP you used and Shenzhou were produced on the same assembly line. This is normal.
Since what you bought is genuine, there is nothing to worry about. Everyone uses the same thing, and what you bought abroad is also made in China.
