> Can you share the values of change-major-mode-hook and org-mode-hook?
I search change-major-mode-hook and org-mode-hook by C-h v(describe-variable).
the result is

```
change-major-mode-hook is a variable defined in ‘C source code’.

Its value is (font-lock-change-mode t)
Local in buffer *Help*; global value is
(global-company-mode-cmhh yas-global-mode-cmhh smartparens-global-mode-cmhh
ctrlf-mode-cmhh ace-pinyin-global-mode-cmhh meow-global-mode-cmhh
global-eldoc-mode-cmhh global-font-lock-mode-cmhh)

Normal hook run before changing the major mode of a buffer.
The function ‘kill-all-local-variables’ runs this before doing anything
else.

  This variable may be risky if used as a file-local variable.
  Probably introduced at or before Emacs version 19.23.
```

```
org-mode-hook is a variable defined in ‘org.el’.

Its value is shown below.

Mode hook for Org mode, run after the mode was turned on.

  This variable may be risky if used as a file-local variable.
  You can customize this variable.

Value:
(#f(compiled-function
    ()
    #<bytecode 0xbfc639b2ee0448f>)
   #f(compiled-function
      ()
      #<bytecode 0x361e3d66626201b>)
   rasmus/org-prettify-symbols org-fragtog-mode org-indent-mode valign-mode
#f(compiled-function
      ()
      #<bytecode 0x1e1b158dce77c68>)
   #f(compiled-function
      ()
      #<bytecode 0x1e1b158c9df1068>)
   org-babel-result-hide-spec org-babel-hide-all-hashes)
Original value was nil
```
