Beijing is the capital of China, in ancient times many dynasties such as the Yuan, Ming and Qing dynasties as the capital, here there are a lot of historical and cultural relics, when the People's Liberation Army did not directly attack Beijing, but also in order to better protect the city of Beijing, do not want to be destroyed, and after the liberation of New China, it as the capital, then the problem comes, as such a city representing the symbol of the country, its construction is particularly important, for this reason many experts and scholars have different opinions.

At that time, There were a lot of walls in Beijing, although in the war many walls were destroyed and crippled, but there were still many intact walls, the ancient city walls were used to resist the enemy's attack, in that era of guns and tanks, surrounded by thick walls, is a kind of protection for themselves, but with the development of the new era, it is obvious that this kind of wall is contrary to the times, and it does not reflect its significance at all.
Then around the end whether to demolish the Beijing city wall, everyone has different opinions, the most representative of which is Guo Moruo and Liang Sicheng, the two of them are in a state of opposition, Guo believes that the Beijing city wall is a product of the feudal period, has a certain impact on the future construction of new China, so it must be demolished. Liang believes that this is a symbol of a country and a nation, they have far-reaching cultural influence, are valuable assets, and should be protected.
And finally took the former view, demolished the Beijing city wall, in fact, the two of them, in the opinion of experts, are not wrong, are reasonable, Liang Sicheng wants to protect the cultural heritage is not wrong, in fact, the city wall can survive with modern cities, such as xi'an we see today, it well retains the city wall, there is no violation at all.
And Guo Moruo's view is also correct, at that time China had just developed, the country was not rich, if you want to keep the city wall, it is necessary to pay a great price, money is a huge difficulty, we must know, if you do not demolish the city wall, you have to spend a huge amount of money to repair the city wall every year, which consumes a lot of human and financial resources and material resources, but for China at that time, it is simply unaffordable, there are not enough resources to build.
Liang Sicheng was considered from the perspective of a constructionist, and at that time, Guo's statement actually caused many people to be dissatisfied, he said that it was a remnant of feudalism, according to him, it was not the Forbidden City that had to be demolished, it was obviously with personal selfishness, and in the end, although the state adopted Guo's view, it was actually considering a lot of situations, and it was impossible to determine that the ancient city wall was really a remnant of feudalism.
