Why is China's traditional culture open?

In the modern history of our country, because the national government stood still and failed to enliven and open to the outside world, many international advanced science and technology failed to be exchanged and popularized quickly and well, but were defeated by its own gunpowder and compass (fully improved and utilized by other countries). China has been enslaved, oppressed and exploited for many times and for a long time, which is why he is behind closed doors.

Reform and opening up is a bridge between us and the world. Only in this way can we quickly integrate into the world collective and learn and develop better! ! !
