swallow one’s resentment and choke back one’s sobs; endure insults and injuries ? 自古皆有死，莫不飲恨而吞聲。(江淹《恨賦》) Death has been a common occurrence since ancient times. They all have tolerated their enmity and gulped down their sobs.
飲恨吞聲yǐn hèn tūn shēnɡ
把仇恨咽到肚里，強忍著不敢哭出聲來。形容遭受壓迫，忍受痛苦，不敢公開表露。swallow one’s tears, endure insults and injuries, harbour hatred in the heart
