I bought Li Ning's basketball shoes and running shoes before, and the running shoes are Li Ning's L logo. That basketball shoe, because it is O 'Neill series, is O 'Neill's icon on the insole. Also, by the way, buy Li Ning from Taobao instead of going to Haole. Go to Li Ning Guxing and Li Ning official website.

LZ Imagine, if the shoes are defective, how can you mark B under the insole instead of on the shoes or the shoe box? Or is it directly isolated?

Mark the soles of shoes, so that employees can't tell which pair is good and which pair is defective, which is easy to make mistakes. Therefore, this handwritten' B' should not be marked with defective products, but should come from a unique production line or production class. General manufacturing plants have Class A and Class B..

Of course, in order to better confirm whether there are defects, LZ can carefully observe the workmanship of each joint of the shoe, especially the glue joint. If defects are found, they can be returned directly. If there are no obvious defects, the probability of proving defective products is not high, maybe there are some hidden defects, if they are hidden defects.

I believe OK shoes are missing more or less. LZ should know that the quality inspection of assembly line production is to check more than a dozen pairs of shoes in one minute. How carefully can employees be selected in such a short time?
