From the content point of view, Qing, please, Qing and Qing are all pictophonetic characters, and the pronunciation is very close to the word "Qing" on the right. Among them, the word "very close" is rigorous, almost close, with differences but little difference. If it is "the same", it is not in line with the actual language. With the evolution of language over time, it is normal that the same sounds in pictophonetic characters are not exactly the same. In modern Chinese, the initials and finals of "Qing" and "Qing, please, Qing and Qing" are the same, but the tone is different from some words, so it is more appropriate to use the word "very close".
