I've set the new HOME with the following method, but it doesn't get
the same testing result as reported here [1]:

#!/usr/bin/env bash
:; env myhome=$(dirname $(dirname $(realpath -e $0)))
proxychains-ng-socks5 /usr/local/bin/emacs -Q --load $(realpath -e $0)
-- "$@"; exit

(setenv "HOME" (substitute-in-file-name "${myhome}"))
;;Bootstrap straight
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el"
user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))
(straight-use-package 'use-package)
(setq straight-use-package-by-default t)


(use-package company
  :demand t
  :hook
  (after-init . global-company-mode))
