Xiaohua Che, founder of Kaiyu Jewelry and current council member of Dongguan Metal Jewelry Industry Association, comes from Jiangxi province. In 2006, he entered the jewelry business through his wife's family, working alongside his brothers. Guided by the principle "master what you do, love what you master," he has devoted himself to technical innovation and maintains rigorous production standards. Though a health condition once required ICU care that temporarily halted factory operations, the "hum of machinery" has become the rhythm of his daily life - not just the sound of equipment, but what he describes as "the pulse of fifty families' livelihoods," a sound that gives him deep reassurance.
