First of all, Renshui was born in Uzuki, which is a prosperous water and river. It likes Mao Mu to show off its beauty, because Mao Mu is Renshui's "wounded official", who represents intelligence, talent and flexibility. Secondly, Mao Mu is Lishui's "sheep blade", which represents calculation, means and determination. Therefore, people with sheep blades in Lishui are exquisite, tasteful and ambitious. But it is forbidden to use wood to make a fire, because wood is a "partial print" of water, representing paranoia and inhumanity. Therefore, people who are reluctant to pay the yen are afraid that the wooden fire in the eight characters will appear at the same time, forming a situation of "fire and water fighting". Under this pattern, people who are unwilling to pay yen have great emotional ups and downs, and it is difficult to achieve great things.
To sum up, Renshui and Mao Mu are a kind of relationship and need to develop together in balance and restriction.
