For the past two years, 8－year－old Harli Jordean from Stoke Newington, London, has been selling marbles(弹珠)．His successful marble company, Marble King, sells all things marble-related—from affordable tubs of the glass playthings to significantly expensive items like Duke of York solitaire（独粒宝石）tables—sourced, purchased and processed by the mini－CEO himself.
“I like having my own company. I like being the boss,” Harli told The Mirror.
With profits now in the thousands, “the world's youngest CEO” has had to get his mother and older brothers to help him meet the growing demand.
Harli launched Marble King after swapping（交换）marbles at school led to schoolchildren depleting(削减) his marble collection. Yes, he literally（确切地）“lost his marbles.” Harli and his mother, Tina, turned to the Internet to find replacements.
Harli saw an empty space online: the marbles he wanted were hard to find. Within months, Harli had his own marble－selling website and orders started pouring in.
Tina says her son's obsession(迷恋) with marbles started when he was just 6.
“His obsession became so big we started calling him the Marble King, so when he wanted to set up a website it was the natural name for it，” she told The Sun.
“I never thought it would become so popular—we are struggling to cope with the number of orders at times.”
The 8－year－old boy has his sights set on expanding his business and launching his own brand of marbles.
“Sometimes his ideas are so grand we have to scale them back a bit. But his dream is still to own Britain's biggest marble shop and open stores around the world.” Tina told The Daily Mail.
