There are several wrong references there:

    .../Documentation/translations/zh_CN/mips/booting.rst:5: WARNING: undefined label: booting (if the link has no caption the label must precede a section header)
    .../Documentation/translations/zh_CN/mips/features.rst:5: WARNING: undefined label: features (if the link has no caption the label must precede a section header)
    .../Documentation/translations/zh_CN/mips/index.rst:5: WARNING: undefined label: index (if the link has no caption the label must precede a section header)
    .../Documentation/translations/zh_CN/mips/ingenic-tcu.rst:5: WARNING: undefined label: ingenic-tcu (if the link has no caption the label must precede a section header)

Replace them by :doc: markup, which won't require to add anything
extra at the existing documents.
