Xiao Song and Duanmu were supposed to report to Sister Dai in mid-October.
However, firstly, the infrastructure at Sister Dai's place wasn't done yet, so there wouldn't have been a place to work.
Secondly, the old monkey was reluctant to come down the mountain. The last time it was sent down, it almost drove the person taking care of it insane, so it had to be brought back up the mountain.
When the animal shed at Chen Ying's was finished, the old monkey was likely to move there for its retirement.
Professor Bai came over, stayed for a day, and then left.
He left Chen Ying a series of certificates and documents, all of which were beneficial for him to independently carry out rescue operations.
The designer who came with Professor Bai was just for show, provided a design plan, and then directly got in touch with the previous Designer Cao to take charge of construction.
