"AIP Publishing is a wholly owned not-for-profit subsidiary of the American Institute of Physics (AIP)." Here are several websites of AIP: https://www.aip.org/, https://publishing.aip.org/, https://publishing.aip.org/china/ (redirected from https://china.aip.org), https://www.scitation.org/, https://aip.scitation.org/. It is not a predatory publisher. The journals of AIP are highly recognized.
It is one of the many online publishers that exist, there are from all countries, Germany, Italy, Spain and as your example, from China. They are all reliable, you just have to agree to the commercial royalty distribution contract. I once published something with one of them, it does not give you any financial benefit, but you get good publicity from what is written.
