In 1966, I was only 3 years old. But I do remember the terrible scenes of Culture Revolution, which must be in the winter of 1967 or the Spring of 1968.
In 1970, the situation was not very crazy and I went to elementary school. But the atomsphere was still very tense. From my childhood, I learn to watch at my own mouth to avoid big troubles. Perhaps this is a positive part I learned as a child in Mao's time.
It seems that you are about 5 years older than I am or more.
