When Yang Yunyi was a child, his mother, "Sister Cao," due to her busy work schedule, the time they spent together was very limited. They were later separated after Sister Cao was stationed in Egypt to work on its new administrative capital built by China State Construction Engineering Corporation (CSCEC). In 2019, Yang and Sister Cao were finally reunited in Egypt.

These past few Mid-Autumn Festivals, they could only see each other online. But now, they put on "hanfu" together, make lanterns together, and enjoy the full moon together. According to Cao, the project allows them to reunite overseas and build their dreams together. Check out their moving story.
