The earliest area that was opened up was transportation.
Suizi's family originally had a tractor. After the family moved to Beijing, Suizi didn't sell the vehicle but left it for Yu Jingting's subordinates to use during their successful runs in the mountains.
During this time, the young couple made a good profit, and Yu Shuisheng and his wife didn't take any of it, treating it as pocket money for the young couple.
Later on, Yu Shuisheng and his wife didn't inquire about how the tractor was used and even forgot that they had such a bulky asset at home.
They forgot, but Suizi didn't.
Using this tractor, she had Yu Jingting's former followers ferry mountain products for two years. When the time was ripe for the national opening of the transportation industry, she quickly sold the tractor. Along with the money saved over these two years, she spent 30,000 to buy a heavy-duty truck in cash.
