In Korea, the Ryu Family is second only to the Fu Family in terms of martial arts lineage. Although Liu Xianhe's generation was somewhat underwhelming, and now he's the only direct descendant still practicing martial arts, if you include the Ryu Family's collateral branches, his father Liu Xianhe is still the third strongest in the family, only behind the current Family Head, Patriarch Liu, and the old butler of the Ryu Family, both of whom are grandmaster-level experts.
Those two were figures from the previous generation, already grandmaster-level experts. Liu Junhao naturally wouldn't count them among the martial artists of the Ryu Family because the gap was simply too large, rendering any comparison meaningless.
