Can others use the green door of the chain home?
You can't. The green door head of the chain home is a visual logo of the chain home network, which can only be used by the chain home itself or the institutions or individuals authorized by the chain home. Other people or organizations use the green doorknob of Chain Home without authorization, which will be suspected of infringing on the intellectual property rights of Chain Home. Chain Home has the right to ask it to stop using it and investigate its legal responsibility.
