Who knows about Sudan?

I have worked in Sudan for two years, and I can tell you the following:

1. If you are in big cities such as Khartoum and Madani, there will be no chaos and many thieves.

2. Every year from April to June, there are serious sandstorms in Sudan. The annual high temperature is 1 1 month, only 1 month without air conditioning and 1 week with coats.

3. People in northern Sudan are friendly to China, while people in southern Sudan are hostile.

4. To work in the local area, you need to be vaccinated against various epidemics. Don't travel alone, take some small change with you just in case.
