都是酸牛奶装什么特仑苏都是白开水装什么优乐美
[dōu shì suān niú năi zhuāng shén me tè lún sū dōu shì bái kāi shuĭ zhuāng shén me yōu lè mĕi]
This phrase expresses dissatisfaction, possibly sarcasm, saying 'if you're just sour milk why pretend to be high-quality milk (Tehelan, a famous dairy brand), if you're only plain water why pretend to be premium tea drink (Ulemai).' It's a critique of pretentiousness or misrepresentation.
