Gu Zichen didn't expect his five-year-old sister to be so smart. She even knew to send people to investigate him?
Although his biological mother was a lowly palace maid, she entered the palace at the age of six and worked as a weaver.
Every day, she worked with satin and fabric and did some embroidery work for the nobles in the palace.
He remembered that back then, his mother wasn't doted on and Gu Yihan had many consorts and sons.
He was the least eye-catching one.
Therefore, his mother would always secretly stuff some silver to the people from the Palace Affairs Bureau when they sent clothes monthly.
She hoped that they would give her some leftovers from the good satin so that she could use them to mend the fifth prince's innerwear.
After a while, because his mother was good at identifying fabric, he was also influenced a little.
