I would say Mao zhuxi one of the greatest men in history. He establishs a new China.
We also need to move forward, we will have more great man in the future. Do you agree to me?
China rose and fell many times in past thousands of years. There are times China fell in history but we never lost faith.
The nomad on our north can't conquer us culturally, they are small in population, weak in culture. No matter Xiongnu匈奴, Xianbei鲜卑, Jie羯, Qiang羌, Di氐, Rouran Khaganate柔然, Turk突厥, Khitans契丹, Sushen肃慎, Jurchen女真. All those nomads were culturally absorbed/Sinicized by Han汉, or defeated and disappeared in the history river.
There was one time we almost fell and never come back, that's western colonization and Japanese invasion. The Korea and Taiwan were conquered and absorbed by Empire of Japan, we are supposed to be the next.
The KMT is weak, penetrated by western power, especially the British and US, and bowed to the Japanese. KMT can't win the war without US military aid and logistic support. KMT heavily replied on the west and landlords, oligarchs. KMT by and large is a stooge.
In the opposite, Chairman Mao defeated not only Japanese, KMT, but also US Army, push them back to 38°. Chairman Mao lead the CCP and united 500 millions Chinese, Century of Humiliation Never Again.
When India Nehru aggressive forward policy encroached our land in Aksai Chin, took advantage of our hostile international environment, Chairman Mao gave India a bloody nose.
When USSR threatened us with 1 million strong mechanized infantry in 1960s like nomads did, Chairman Mao responded with nuclear test in 1964 and Thermonuclear test in 1967, Third Front (三线建设). Century of Humiliation Never Again.
When US threatened us in Vietnam, we assisted Vietnamese, threatened US not cross 17°, otherwise it will be another Korea War or even World War. US backed off, lost the Vietnam War. Century of Humiliation Never Again.
Most dams in China were built in Chairman Mao era. Most railway were also built in Chairman Mao era. Most illiterate were educated in Chairman Mao era.
The ill Confucianism(宋儒) since Song宋 was eliminated by Mao. Chairman Mao replaced our thousands years long outdated Confucianism(农耕时代的,基于小农经济的宋儒) with Marxism(工业时代的,基于社会化大生产的社会主义思想)
Chairman Mao is not only a leader, but also state man, master of geopolitics, diplomat, strategist, philosopher and a great poet.
沁园春·雪
毛泽东
北国风光,千里冰封,万里雪飘。
望长城内外,惟余莽莽;
大河上下,顿失滔滔。
山舞银蛇,原驰蜡象,欲与天公试比高。
须晴日,看红妆素裹,分外妖娆。
江山如此多娇,
引无数英雄竞折腰。
惜秦皇汉武,略输文采;
唐宗宋祖,稍逊风骚。
一代天骄,成吉思汗,只识弯弓射大雕。
俱往矣,数风流人物,还看今朝。
Literally, no one on par with Chairman Mao in history, I hope no one in future. China should NOT fall again, we should NOT wish another savior like Chairman Mao.
