面对面接吻背对背牵手
[miàn duì miàn jiē wĕn bèi duì bèi qiān shŏu]
“Kissing Face-to-Face but Holding Hands Back-to-Back” implies the inconsistency between appearance and fact. On one hand, lovers kiss passionately face to face, symbolizing intimacy; on the other hand, holding hands back-to-back implies distance or a gap, indicating complex emotional entanglement within the relationship.
