Why do you think Wang Hong would not know Bravely Descending Divine Sword Palm?
I want him to use a technique with that name.
Depending on how much we want Wang Hong to be, we could say that Lin only fought back with 5% force, or 100%.
And if he fought back with 100%, then Wang Hong isn't just a martial artist from Shandong. There would be more secrets about him.
In fact, I think it would be cool if he can go through a "title upgrade", get rid of the Shandong in his title, since he has become more universal now.
