农夫山泉有点甜恒大冰泉有点咸
[nóng fū shān quán yŏu diăn tián héng dà bīng quán yŏu diăn xián]
It refers to two water brands in China, where 农夫山泉 (Nongfu Spring) tastes naturally sweet while 恒大冰泉 (Evergrande Glacier Mineral Water) has a taste somewhat like salt. Besides, it also hints something similar as: someone might feel good in some situations, and bad in others.
