You can try the below config :-)





(defun eh-org-wash-text (text backend _info)
  "导出 org file 时，删除中文之间不必要的空格。"
  (when (or (org-export-derived-backend-p backend 'html)
            (org-export-derived-backend-p backend 'odt))
    (let ((regexp "[[:multibyte:]]")
          (string text))
      ;; org-mode 默认将一个换行符转换为空格，但中文不需要这个空格，删除。
      (setq string
            (replace-regexp-in-string
             (format "\\(%s\\) *\n *\\(%s\\)" regexp regexp)
             "\\1\\2" string))
      ;; 删除粗体之后的空格
      (dolist (str '("</b>" "</code>" "</del>" "</i>"))
        (setq string
              (replace-regexp-in-string
               (format "\\(%s\\)\\(%s\\)[ ]+\\(%s\\)" regexp str regexp)
               "\\1\\2\\3" string)))
      ;; 删除粗体之前的空格
      (dolist (str '("<b>" "<code>" "<del>" "<i>" "<span class=\"underline\">"))
        (setq string
              (replace-regexp-in-string
               (format "\\(%s\\)[ ]+\\(%s\\)\\(%s\\)" regexp str regexp)
               "\\1\\2\\3" string)))
      string)))

(The space is valid, of course, if the characters on either side of the line breaks are Roman or [I would guess] Cyrillic as well.)

>(Side note: Exporting to a LaTeX buffer shows that the line breaks have been copied into the .tex document as is -- but, provided that you have a `usepackage{xeCJK}` in the preamble, LaTeX produces correct, space-free output. So -- Org "gets away with it" because of LaTeX's handling of CJK text. It seems for ODT, Org needs to handle the spacing within its own logic.)
