Does it support reading and modifying the value of the enhancement attribute, I've tried a lot but I can't read it.

As shown in the picture, the value of the enhancement attribute is displayed directly, I would like to be able to read and modify it, I don't know if it is supported, thanks!

I don't know what an "enhancement" (damn google translate!) attribute is, and without the test data and your code I can't help - read the issue template I provided!

doc = ezdxf.readfile(f)

block = doc.blocks.get('EPLFRAME')
for e in block.entity_space.entities:
    if 'prompt' in e.dxfattribs() and e.dxfattribs()['prompt'] =='项目描述':
        print(s.dxfattribs())

Here's the source file, and the demo.
I printed one of them, and I can only get the following information,

{
    'handle': '1E4', 
    'owner': '1D7', 
    'layer': 'EPLAN451', 
    'insert': Vec3(101.0, 9.0, 0.0), 
    'height': 2.504999999999999, 'text': '14_10011', 
    'style': '宋体', 'prompt': '项目描述', 
    'tag': '14_10011', 
    'flags': 0, 
    'lock_position': 0
}
