A mainland traveller has accused Hong Kong of being "troublesome" after he was fined HK$1,000 for trying to take an extra can of milk powder over the border. Lin Youzhu, 46, a manager who earns 140,000 yuan (HK$172,600) a year, claimed he bought the infant formula for his month-old baby. He said his final destination was Macau but he had stopped over in Hong Kong. After paying the fine, he accused the Hong Kong government of charging him without confirming whether the formula was for domestic use or for sale. "It was so troublesome. It would not be fair unless you can be certain of the facts and carry out further investigations to substantiate [the charge]. It is getting so annoying," Lin said. "The mainland has been giving Hong Kong all the resources, but Hong Kong does not even allow us to buy an additional can of milk powder."
