巴黎鐵塔下的承諾櫻花樹葉下的諾言
[bā lí tiĕ tă xià de chéng nuò yīng huā shù xié xià de nuò yán]
It literally means 'promises under the Eiffel Tower in Paris; vows under cherry blossom leaves.' These phrases combine romantic imagery elements like iconic places (Eiffel Tower in Paris), beautiful scenery (fallen cherry petals), together with promises, suggesting deep, lasting commitments associated with such poetic settings.
