I'm a dude in his 50s now (that still feels weird to say), and I have to pee all the damn time. Going out in public always involves studying the restroom situation ahead of time. Even so, I've pee'ed in countless alleys, side-roads, and parking lots; I'm always discreet as possible, but I still don't like to do it.
New York City is the absolute worst. Disgusting doesn't bother me, but why are the damn subway restrooms always closed?!
Vandalism and drugs. It doesn't have to be everyone - just enough people - but if you had to go clean up blood and feces smeared over everything once a week, would you stay in that job?
I had a similar problem at probably a similar age. Turned out that it was an enlarged prostate. Had surgery and things are much better now. The urologist said he typically saw it with men 10 years older.
One bad side effect was that urine was being held in my kidneys, damaging them. So I'd urge you to get it checked out sooner rather than later.
This is a symptom of hyperglycemia or ketalacidosis. This happened to me when I was a kid, as will typically happen to undiagnosed diabetics. Have you thought of testing your blood sugar (faster) or A1C (tests average over longer period)? I don't speak Chinese but I heard of this, 糖尿病
