人潮拥挤我感受不到自己
[rén cháo yōng jĭ wŏ găn shòu bù dào zì jĭ]
In a bustling crowd of people, the individual feels invisible, overlooked, or disconnected from the surrounding lively environment and society at large, emphasizing a sense of isolation within crowds, or struggling to find a sense of self among others.
