These are two series of Langsha socks industry. Langsha includes many sub-brands, such as Shi Lang Wesson, Livingstone, Queen Bertha Anlun Langsha and Red Gold Langsha. If you buy it, I recommend buying the Langsha red series, which is of good quality in Langsha. Don't buy Longsville and Lifu, the quality is not so good and the defective rate is high. In spring, Langsha's socks may go up in price. When buying, you must look at the label on the back of the socks, that is, the ingredient list on the back of the socks package. Langsha has a kind of cotton-free socks in spring, which costs about 3 yuan a pair. Don't buy them. They are uncomfortable to wear. If you wholesale here in Shandong, you go to Qingqing business in Jinan, which is a provincial agent. Many Langsha socks wholesale in Jinan West Market are not genuine.
