Here’s some info that I was able to find on the style through the magic of the internet forums.
It would seem that the style started out in Yintao, Shandong and has a lineage in Qingdao, Shandong, China since 1945.
The lineage basically looks like this:
He ShunChang (CE 1833 - 1922)
Mao LiQuan also known as Mao Zhen Xiu (CE 1855 - 1967 started the lineage in Qingdao since 1945)
Sun YiZhai (CE 1935 - ) and many others
Song ZhenRen and many others
The main emphasis of this style is to be symmetric as well as fights with both sides. Cirriculum wise, it has about 33 forms. It is quite similar to the HK 7 Stars on a quick glance.
