Lu Jiao didn't want to convince them to go all in. Though leech keeping was profitable, there were lots of risks. She didn't want to be responsible if they lost money.
Lu Jiao said to the leaders, "For the first year, keep it small. Other than risks, there's the question of where to get the leeches. You can focus on leech reproduction in the first year."
The leaders nodded and agreed, "Okay, then, Yunjin's wife, how much land do you think we should clear for this?"
"Try 2 acres first."
Two acres was an acceptable figure to the villagers and everyone nodded.
Lu Jiao continued, "Before we start this, I have a few things to say. First of all, I am going to be teaching my second brother-in-law the techniques of leech-keeping. He'll be responsible for the leeches."
The leaders didn't object, "Okay, but isn't it too much work for him?"
