卖火柴的老年痴呆
[mài huŏ chái de lăo nián chī dāi]
In Chinese literature, '卖火柴的小女孩'(The little girl selling matches) refers to Hans Christian Andersen's famous fairy tale The Little Match Girl, which has sad tones. This name connects this classic story with 'elderly dementia', symbolizing loneliness and sadness in old age, as well as forgotten past beautiful memories.
