Tsuen Wan, huh.
Growing up, I was told not to go north of Mong Kok, and I think I’ve only been to Sham Shui Po couple of times to buy pirated software 
So yes, I missed the boat on Shen Zhen big time. Back then, Sha Tin was also considered “up & coming” but we laughed it up as boonies. I’d imagine Sha Tin has finally “come” now?
