Thanks Alex for posting this. Suenming (actually his name is Sun Tat-Ming, or Sun Daming if you want the Mandarin version) is one of the guys from the HK group under Zeng Hanjie. However, as Alex says he makes regular trips to Shanxi to study with Song Baogui shibo (son of Song Guanghua).
Agree that the Zhao family have refined and built on what they learnt from Song Tielin - and I am a huge fan of M Zhao Yongchang and Zhao Chuanhui shibo - but I would caution against reading too much into the differences in shenfa. A lot of the differences are down to individual expression, and for example Gary See in HK, who has studied with the same teachers as Suenming, has a fajin and expression which almost looks like Tian branch people.
One thing to note - no crazy shaking in this video - hope Song style can shake the damage done by Tadzio G!
