奈河桥等倪轮回
[nài hé qiáo dĕng ní lún huí]
In Chinese folklore, 'Naihe Bridge' is where souls meet in the afterlife. 'Waiting for you on Naihe Bridge until we are reincarnated' expresses the depth of one's loyalty and eternal love. It shows a person willing to wait not just in this life but across all reincarnations.
