With such planning, there is no need to worry about the winter feed for the cattle and sheep, nor is there any technical difficulty in constructing their sheds. The only issue is safety.
"...Raising cattle and sheep on the river beach, the place is vast and the view wide, and with one side bordered by the river, it actually is much safer than grazing them in the mountains. Also, due to the terrain, there's really no need to fear theft."
"But the cattle and sheep might wander off on their own, and you still need to guard against others with ill intentions... How about hiring someone to keep an eye on them every day?"
Song Tan furrowed her brow, "Just to keep an eye on them?"
"Pretty much," Professor Song replied with a smile.
"If someone has experience, they would know that in a herd of cattle, as long as the leader is corralled within a certain area, the others won't easily stray."
"So you really only need to keep an eye on them."
