I have seen the calligraphy works of the old man Chen Jinfa, which belong to the category of "beautiful" calligraphy style, but there is often a kind of "neurotic" brushwork between the lines of calligraphy works, that is to say, spending a lot of money is often unexpectedly exciting, which should do more harm than good.
Chen Jinfa's calligraphy works are valuable for collection, so they should be properly preserved and not framed as much as possible.
