半斤八两 (Bànjīnbāliǎng)

Background
"Bànjīnbāliǎng" is an original Luo Tianyi song that tells the story of Tianyi being alone at an amusement park as she recalls her past memories. In those memories, two people (one of them being Tianyi) grew up with in the same neighborhood and hated one another. They tended to be sarcastic and were overall mean to each other. But when the time came that one of them was leaving, Tianyi felt regretful about the past and wanted to redo their relationship. In the end, Tianyi is back in reality, then claims she's not as "bànjīnbāliǎng" as the other person.

The title has a specific meaning that is used to describe two very similar people that they could not really be compared; two people of around equal personalities. However, the term has a negative meaning.
