What does cultural authenticity mean when a city like Hanoi rebuilds its Old Quarter facades every few years for tourism? I walked through Hoan Kiem last week and noticed how the noodle shops now serve the same Instagrammable bowl of pho, priced for foreigners, while the old ladies who used to sell banh cuon on the corner have moved to the outskirts. Some argue this preservation keeps heritage alive, but I wonder if we're just curating a theme park version of our own culture. Is it possible to modernize a city's identity without losing the messy, living traditions that made it authentic in the first place?
