I heard that Lan Zhanfei was kidnapped by Chinese people in South Africa. When traveling alone, one really needs to be low-key, especially in countries with unstable security. Friends in the crypto circle should be more careful—the convenience and anonymity of cryptocurrencies are advantages, but can become fatal weaknesses when being robbed or kidnapped. When going out, it's best to avoid remote areas and minimize contact with strangers. Never live-stream your travel itinerary; show off only after you are in a safe place.
