How to get to the second city in San Andreas?

The second city is San Hui Luo, which is based on San Francisco, in the left half of the map, a little north of Millennium Mountain. It will automatically unlock when performing the task of burning virus in Therus, and will enter the city on the way. If you don't do this task, there are roadblocks on the road, and you can walk all the way along the coastline on the left side of the map on the left side of the waterway. There is a long beach coastline on the left side of Shenghuiluo, which can be directly walked up. But after arriving in the city, there will still be four-star wanted criminals. After leaving the city, the wanted criminals will be reduced to three stars. You can also steal planes from Los Angeles airport. In the early stage, it seems that only one wing can fly, and other planes are locked, which can only be unlocked after flying to driving school.
