A little bit of googling in Chinese reveals that Wang Xiliang's Che style comes from one of Che Yizhai's senior disciples, Fan Yongqing (樊永庆). The lineage goes Che Yizhai -> Fan Yongqing -> Yang Yongwei (杨永蔚) -> Wang Xiliang. This is quite an interesting branch for a couple of reasons: (i) Seem to have maintained a fairly complete syllabus of weapons, empty hand forms, zhan zhuang, sparring practices, and (ii) videos from practitioners of this branch (e.g. Yang Yucheng杨玉成, Yang Yongwei's grandson), seem to have very good shenfa with good whole body connection.
Good video of Yang Yucheng here:
