How much is the level of calligrapher Dennies Hu's works?

No matter the works of any painter or calligrapher, if you want to know the price, you must first see the real thing. Before seeing the real thing, no matter how much the work is worth, it is illusory, unreal and unreliable. In particular, Runge is an unreliable reference, mainly depending on the market and my own understanding of the work.
