1. The shoes you bought are old models or limited editions of Li Ning. These styles may not have Li Ning's logo, but they have special logos or designs.
The shoes you buy may be fake or inferior. If you have any questions about the shoes you bought, I suggest you contact Li Ning's customer service or return them.
The shoes you bought may be shoes of other brands, but they are similar to Li Ning's styles, so the merchants printed Li Ning's pinyin or other similar signs on the shoes.
If you are in doubt or dissatisfied with the shoes you bought, I suggest you contact the seller or Li Ning customer service as soon as possible to solve the problem or return them.
