问:听说开网店生意火爆赚钱容易,我弟弟便在美国一家购物网站买了一些婴儿洗浴用品、婴儿食品,然后开了一家网店进行销售。他的生意很好,顾客很多。随着生意越来越红火,他不断扩大经营范围。有一次,一个朋友的小孩感冒咳嗽,用了从美国寄来的儿童止咳糖浆后效果很好。弟弟得知后,便在网上销售这种药。不料,近日他突然被拘捕了,罪名是销售假药。请问,从美国进口的药明明是真的,怎么变成假药了呢?弟弟这样做真的违法了吗? Q: I heard hot and easy to open shop business, my brother bought a baby shower at a shopping site in the United States, baby food, and then opened an online shop for sale. His business is very good, a lot of customers. As business gets more prosperous, he continues to expand its business scope. Once, a friend’s child coughed with a cold and used cough syrup from a child in the United States. After my younger brother learned that he sold the medicine online. Unexpectedly, he was suddenly arrested recently, on charges of selling counterfeit drugs. Excuse me, the drug imported from the United States is obviously true, how to become a fake it? Is it really illegal to do so?
