Yes, public transportation is quite popular in China. The country has developed a massive network of buses, trains, and subways that are used by millions of people every day. It's really affordable and convenient for everyone, especially for those who live in big cities and need to commute daily. This helps a lot in reducing the traffic jams and pollution in urban areas.

No, public transportation isn't as popular as it could be in China. With the economic boom, more and more people are buying cars, which seems more convenient to them. Especially in rural areas, public transport options are quite limited, which forces people to rely on personal vehicles. Also, in big cities, despite having a good network, traffic congestion can sometimes make public transport less appealing.

It depends on where you are in China. In big cities like Beijing or Shanghai, public transportation is extremely popular because it's efficient and helps avoid traffic jams. However, in smaller towns or rural areas, it's not as common because the networks aren't as developed, and people often prefer using their own cars or motorcycles.
