The old man had a few friends who got involved due to overseas family connections. Zhou Jiao helped them get relocated to good places, and also occasionally sent anonymous packages.

These things were known not only by Zhang Guoqing but also by Zhou Xiaozheng. After all, Zhou Jiao always consulted with them on matters to keep the big picture in mind, but she kept it from Miao Lishan.
It wasn't that she didn't trust her mom's character, but in those times, the fewer people who knew, the less worry there was.
