Although "thrifty" and "stingy" are similar to some extent, their meanings and contexts are different. "Thrifty" usually refers to the reasonable and economical use of resources, emphasizing a positive attitude towards life and cherishing resources; while "stingy" has a derogatory meaning, usually referring to excessive thrift and reluctance to spend money, and is usually related to stinginess and selfishness. Therefore, if the context emphasizes the concept of reasonable thrift, it is more appropriate to translate it as "thrifty"; if it emphasizes being too stingy, then "stingy" is relatively appropriate. Therefore, it depends on the specific situation.
