Brother is here. Is it the same organization as the brother and sister gang?

Does the subject want to ask, "Brothers and sisters are an organization?" ? It won't open. Gangge belongs to a software of Gangge Education Consulting Co., Ltd., whose company is in Guangzhou, and Gangge and Gangjie belong to a software of Gangge Information Consulting Co., Ltd., whose company is in Beijing, so it is not an institution. Brother help app and brother help app are both college entrance examination artifacts.
