In the end, Cai Ying was sent back by Mao Dao.
She had chosen it herself. She wanted to marry the old man!
She wouldn't choose to be a slave.
When Mao Dao returned home and saw his parents, he knelt down on both knees and kowtowed three times to them.
"Father, Mother, your unfilial son, Mao Dao, is back! I know I was wrong. Please forgive me for my past mistakes!"
Seeing that their son had become sensible, Mr. and Mrs. Mao quickly helped him up from the ground.
"You're sensible and have thought it through! It's good that you're back!" Mr. Mao said as he helped his son up with tears streaming down his face.
As the saying went, a prodigal son that changed his ways was more precious than gold. Although his son had been a little shameless in the past, it was fine as long as he changed his ways.
Actually, Mr. and Mrs. Mao had seen the changes in their son during this period of time.
