Criticism should be offered in the spirit of curing the illness to save the person.
Tips
usage
Two uses: (1) literal, describing medical practice; (2) figurative, the principle that criticism and discipline should aim to reform, not destroy, a person. The figurative sense is standard in HR, education, and Party discipline discourse.
grammar
Two parallel verb-object phrases: 治病 (treat illness) + 救人 (save person). The second clause expresses the goal of the first - a common chengyu pattern: 修身养性, 扶贫济困, 劝善惩恶.
