Shoes and clothes are relatively difficult to identify. If you have seen the high imitation, you can really get the real thing, but after a long time, these two kinds are still easy to show. You can tell them from the price. YY's equipment is never cheap, clothes are generally above 200, and the lowest end of shoes is at least 300+.

As for the racket, the more conventional method is to look at the bottom cover first to see if YY's LOGO line is clear and unambiguous. There will be Japanese words under the LOGO, which will generally be exposed here. I can't carve the word Japan, and the overall lines are softer, especially the hook of J won't bend much. For example, if there are some numbers or other signs on the bottom cover, it will definitely be a fake YY. However, the method of inquiring the authenticity through the photoetching number of the racket (only the CH version can be inquired) is no longer effective, because there are a large number of fake YY in the market using the photoetching number of the real YY, and this method is no longer feasible. LZ can also be judged by observing the paintings of the whole racket. Generally, fake YY is definitely not as real as painting water, and the color and pattern will be very rough. If you are not AT ease here, I can recommend you to choose AT series rackets of at500 or higher. At present, this series of rackets have no forgery technology to imitate the TI armor of the racket head, so it is very simple to identify. Another way is to look at the price. Generally, the price of fake YY is not higher than 200, and the lowest model of any real YY is at least 300+ RMB. Of course, some unscrupulous merchants will sell fake YY at high prices. This needs attention.

Having said that, the more practical way is to buy a racket from a seller designated by YY, and you can bring a friend who knows the racket for your reference. I hope my answer will satisfy you.
