Donggang Co., Ltd. and China Tennis Association jointly launched the "Blockchain Internet of Things" certificate product, which is currently in the implementation stage

Donggang (002117) responded to investors' questions on the interactive platform, saying that the "Blockchain + Internet of Things" certificate product jointly launched by our company and the China Tennis Association did not meet the major contract disclosure standards, so the company did not make a separate announcement. The cooperation is currently in the implementation phase, and the project's operating income will be determined by the issue of root certificates. The specific fee standard between this certificate and members is determined by the China Tennis Association or its operating agency. Our company only provides technical services and related products to the operating agency.
