特仑苏也不一定是纯牛奶
[tè lún sū yĕ bù yī dìng shì chún niú năi]
'Telesu isn't Necessarily Pure Milk', Telesu being a popular Chinese brand of pure milk. In recent years, there have been cases of adulteration in milk products across China, leading to mistrust. Therefore, it hints at skepticism towards purity.
