...... According to the data, in the first half of this year, the number of foreigners entering the country at various ports increased by 152.10%, and more than half of them entered through the visa-free policy. It can be said that this policy not only makes it easy for more foreigners to visit China, but also attracts a group of "visitors" who are curious about China. They use their own perspective to discover and record China, and then share what they have seen and heard with the world.
