You can go, but it will be inconvenient. Frequently check the temperature and check the green code, and many indoor venues and exhibition halls are closed, travel agency tours are suspended, shuttle buses on some lines are blocked, and restaurants are not normal.
For travel? The experience will not be good. The focus of all aspects is on the prevention and control of the epidemic, rather than receiving tourists, so food, accommodation and transportation are very reluctant. It's better to wait until 5.1 to consider it.
