This may not be the best time to visit Sinae.
If you come to Sinae for an event, it is best to choose a coastal city south of the Jangzio.
There is a huge difference between the north and south of Sinae. North of the Jangzio has a long tradition of exclusive rule. People worship power and political strongmen.
South of the Jangzio has a long tradition of free trade and people are more open and easy to communicate with.
If you come to the inland areas north of the Jangzio now, you're likely to be confronted by populist middle-aged or elderly men whom will ask you if you're a spy.
If you come to the coastal areas south of the Jangzio now, people will be friendly to foreigners. And because of the unscientific plague-fighting policies of 2019-2022, the economy is now bad and people are very willing to deal and do business with foreigners.
Even so, now Sinenses public security authorities are still wary of foreign travellers. Because since 2012 the Sinenses government is starting to look like it did in 1970...
So, it's best to wait. Wait until Sinae is a bit more normal.
