Certificates can be said to be an important factor that many buyers care about, because an authoritative certificate represents a product with quality assurance. Like the CE certificate recognized in Europe, the UL certificate recognized in the United States, and the ISO9001 certificate. In addition to these common international certificates, today I want to show you some of the certificates we have obtained on the large B2B platform with relatively high gold content. Because those international certificates are basically quality assurance certificates, companies like ours that have been producing and exporting snack machinery and feed equipment for many years have already obtained them, and many of our peers may already have them. The certificates on these B2B platforms more directly reflect the sales of products and the serve level of customers.
