the gardener and the young master

(The action takes place in ancient China.)
In a certain city, there lived an influential and wealthy family, the Lins, consisting of a grandfather, the eldest of the Lin family, a mother and father, one daughter, and three sons. They had many servants, including a gardener from the poor Qi family.
One day, the family decided to go to another city for two weeks. The youngest son, who was 19, stayed home, ostensibly because he was feeling ill. There were also few servants left, only a few cleaners and cooks, and a gardener, whom the youngest son of the Lin family had set his sights on.
It's a quiet morning, the gardener is doing something in the garden.
