As everyone, if not some acknowledged that the first incursion of mongolian armies to the east coast of japan, consisted of northern chinese(jurchen/han people) have been conquered by the mongolians as well as subjugating korean pennisula. Only the Southern Song (南宋) was still at rival with the mongolians, however i believe that during the first invasion of japan, the jurchen jin did not use zhan ma dao and only the Southern Song's did. After Southern Song had been conquered by the mongols, the second invasion then would consisted of Southern Song armies with the use of zhan ma dao. The defeat of the second invasion was resulted that the japanese spare the Song chinese because they respect and regarded them as Tang people (唐人) whilst the mongolians they did not spare a single one of them. From my point of view, i would say this is the very starting point of where Song chinese transmitted the making of zhan ma dao and how to utilize them to the japanese.
This is a replica one.

This is one of my favourites, the Yun Nan Zhan Ma Dao used by kang xi emperor.

And another replica of zhan ma dao.
