换汤不换药

繁体換湯不換藥

  1. different broth but the same old medicine (idiom); a change in name only
  2. a change in form but not in substance

“the same old stuff with a different label; change the liquid but not the drugs - a superficial reform”

比喻名称或形式虽然改变了,内容还是老一套。

示例 去了一个段派,复来了一个段派,仍然是~。(蔡东藩、许廑父《民国通俗演义》第一百十五回)
