I too feel a bit saddened too seeing this picture. However, as a frequent traveler to TW, I can assure you Pan, that these girls are NOT into prostitution generally. It’s very common that these young girls are dressed in a sexy outfit to attract their customers (as I understand, most of their customers are truck drivers who just stop by to grab their betel nuts in a few minutes and go off).
Per Google Ai:
“Betel nut chewing is a widespread habit in Taiwan, often referred to as "Taiwanese chewing gum" and associated with the colloquial term "binlan". It's a significant part of the island's culture, though its popularity has also raised concerns about public health. Over a hundred billion New Taiwan dollars are spent annually on betel nut, making it a major economic crop in Taiwan..”
