Open Question: What is Shao Bei Fist (Shao Bei Chuan)?

I understand its a style from the Northern Shaolin school, but I honestly cannot find any information on it, and its not made up because Sammo Hung said he taught it to Louis Fan for the movie “Ip Man” and that its based off of ancient Chinese boxing forms. Is there another name for it or other variations to it, or is there any links to schools or articles about it? If anyone can find anything that would be great, thanks.
