My neighbor's older sister is 37 years old this year, a graduate of a prestigious university, working at a hospital in Shenzhen, with an annual salary of around 300,000 yuan, and an average appearance.

When she was young, she was unwilling to settle, and gradually became a single woman of a "long-term single" in others' words.
Her mother said that someone introduced her to a 35-year-old man working in technology in Shenzhen, with an annual salary of 250,000 yuan, and the conditions were considered matching.
The two met and talked quite well, but when the man asked about her age, she just said 37, and he immediately said it was not suitable, paid the bill, and left.
My neighbor's sister hid in her room and cried for a long time after returning home; her mother said she had never seen her so devastated.
Such an outstanding person, why is she being rejected just because of her age?
