Cambodia's Sihanoukville, this woman, a Vietnamese known online as Nguyễn Yumi, currently works as a prostitute on Vietnam Street in Cambodia. Those men who have been in contact with her should be familiar with her. She deceives people for money and uses drugs under various pretexts. Having contacted her many times before, she would ask for money transfers under various excuses once she got familiar. Moreover, this woman also has AIDS, so everyone should be cautious. On the night of December 16th, around 2 AM, I met her again to confirm, because she had previously told me that she had no sexually transmitted diseases and even showed me her hospital medical report, so I chose to believe her at that time. However, within three weeks, I started feeling unwell and went to the hospital for an AIDS test, feeling as if the sky had fallen. Now I regret it deeply and don't know what to do. Last night, I met her again, intending to confirm once more. After drinking a lot at a bar, I planned to return to the hotel for a good rest. While I was taking a shower, she was messaging her boss. By 5 AM, her boss arrived with several strong men and deceived me out of 6000 US dollars. I am using this platform to remind everyone to always protect their personal safety when outside.
