I used to work for Connor. That is to look at the article number and the type of trademark. Generally, the article number issued by the original factory is relatively simple with five digits. Besides, the trademark should be the kind with a human head, and the sole has the words or pinyin of Kangnai. Secondly, look at the workmanship and price of shoes. The higher price should be from the original factory. Now 7% of Kangnai is branded, that is, the acquisition of miscellaneous brands, so be sure not to be a big head.
