Every TV director wants his TV series to be accepted by the audience. Some of them are purely profit-oriented, while others are ideal and profit-oriented. Whatever the purpose, they must make a profit.
If his TV series is not profitable, then his filming of this TV series may mean that this is the last TV series in his life. Profitability is recognized by attention, and most of his attention is focused on watching his TV series. If his TV series is ignored, then he is a failed director.
Jiangnan Kyushu series novels are all epic series. A director who makes a TV series needs a lot of money and it is also very difficult to make an epic series.
