One of the enterprises is from my hometown, my nanny worked at it
In short, it is talking about three companies, a fish canning factory, an agricultural cooperative and the Mao Zedong Factory, which manufactured the first sanitary vans. It briefly presents the companies and their performance.
It was from a news broadcast,so that's why,it's not a comprehensive overview
It was more of a progress report from the state tv
I edited the title to be more clear
