Which CPU of MIPS did Loongson copy?

Searching for "Loongson plagiarized MIPS R 10000" in the search engine, most of the results are "Chinese Academy of Sciences officially denied Loongson II plagiarism". In fact, the simple problem is that the Chinese Academy of Sciences will not admit that Loongson II copied MIPS R 10000. Just like when Kirin copied FreeBSD, it disappeared without tears, and so did Han Xin. The products made by such poor counterfeiting methods have deceived many people, and its shameless degree can be seen. If they can admit plagiarism, they won't plagiarize, but what they say is meaningless, unless there is proof from a third party, it can explain the problem.

They could have introduced their system architecture to everyone to reduce their doubts, but they didn't. Why? So did Han Xin after he was interrogated. Just because their things are shady, how dare they say what they copied? If I know this, why should I know it?

Originally, they said that Loongson was MIPS kernel in order to make people realize the simplicity and efficiency of MIPS instruction, but later they realized the problem of intellectual property rights and were questioned by MIPS company. In this way, they talk as little as possible about the kernel, because their products are not authorized by MIPS, because they probably bought MIPS kernels from other MIPS licensees, and some people on the Internet said that they were unauthorized copies of MIPS R 10000. Their method is really better than Han Xin's. Hanxin just bought Freescale chips and polished them. It can be said that everything in Hanxin is fake. However, with the progress of society and the development of science and technology, it is definitely not possible to use Hanxin completely, but the Loongson method is better. They got the source code of MIPS kernel, so that they can modify it on the original basis like copying FreeBSD, and then go to fab for production and put their own Logo on it. This method is not easy to be found to be fraudulent. Why? Because even China, a polished Hanxin, has been looking for it for a long time.
