This new term has become popular recently among Chinese netizens and it has a special meaning: getting married without a house, car, diamond ring or a proper wedding ceremony.
Chinese terminology: ‘naked marriage’

Among these “naked” aspects, having no house is the most important, because it usually stands as a symbolic guarantee.
