一杯清酒灌入喉一句再见便永久
[yī bēi qīng jiŭ guàn rù hóu yī jù zài jiàn biàn yŏng jiŭ]
This nickname expresses a poignant farewell with a toast of wine. In Chinese culture, alcohol, especially 'baijiu' (a strong Chinese liquor), has long been used in occasions such as celebrations and farewells. By drinking this wine deeply and bidding final goodbye at the same time, it symbolizes that after the farewell with this glass, it will be a permanent farewell, implying no looking back or meeting again, which carries an atmosphere filled with emotion and decisiveness.
