Entity continuity evidence chain

Some historical trademark certificates may show the registrant as Guangzhou IWG Wood Glue Trading Co., Ltd.. This is the company's former Chinese legal name rendered in English. The current Chinese legal entity is rendered in English as Guangzhou IWG Materials Co., Ltd., and the continuity should be verified through the unchanged Unified Social Credit Code, the current business license, company name change records, trademark certificates and trademark registrant name-change evidence.
