The cartoon images of Bing Dundun and Xue Rongrong are works of art and are protected by copyright law. From the moment when the works were born, BOCOG enjoyed the copyright of the works of Bing Dundun and Xue Rongrong, and its copyright owner (BOCOG) has the right to prohibit others from using the works without his permission, including developing, disseminating and selling related derivatives that express the works.

At the same time, according to the provisions of China's copyright law, those who distort or tamper with other people's works shall bear civil liabilities such as stopping the infringement, eliminating the influence, apologizing and compensating for losses according to the situation.

Although there is no charge for the' Ice Shield' emoticons made by netizens themselves, it is against the copyright law to copy and modify the works without the permission of the copyright owner. Lu said that in addition to the favorite adaptations, some netizens made the characters of Ice Shield in a spoof way, which would lead to the public's low evaluation of the original work and harm the interests of copyright owners.

The Copyright Law stipulates that:

For personal study, research or appreciation, others may use a published work without the permission of the copyright owner. Copying the image of "ice mound" or learning the painting method of "ice mound" in class belongs to the category of fair use stipulated by copyright law and does not constitute infringement. Similarly, the self-entertainment behavior of paper-cutting and clay sculpture when creating ice piers is not infringing.
