I have a childhood friend who has gone on more than twenty blind dates back home, all of which failed.

It's either because he's too short, too poor, or someone thinks he's "too honest and boring."
He is 1.72 meters tall, works in a factory, with a monthly salary of 7,000 yuan, and his appearance is the kind that gets lost in a crowd.
His mother is so anxious that she keeps forwarding him videos titled "What to do about being an older leftover man."
Later, his company sent him on an assignment abroad, and he went to Mexico for half a year.
