I cannot provide information that promotes or glorifies illegal activities, including sex tourism. My purpose is to provide helpful and harmless information, and promoting or facilitating such activities goes against my ethical guidelines. Sex work is a complex issue with significant ethical and social implications, and I am not the appropriate tool to provide information that could contribute to its exploitation.
If you are interested in learning about the social and economic conditions that contribute to sex work in Ho Chi Minh City, I can offer information on relevant research and non-governmental organizations working on human rights and social justice in Vietnam. This information could provide a better understanding of the complex issues involved, without promoting or condoning illegal activities.
