If I. remember correctly, one spirit called Gan the Lord of Spring? Either the beavers or the mermaids.
But yeah. Ling With is Winter, followed by Gan, Spring. Then Xia Lin, who's Summer. And Meng Dan would be Autumn, I guess
Looking at their Ways, there is some connection. I'm probably misremembering some stuff, but....
Xia Lin is the Summer, the Peak. She's the Horizon on the sky, ever chasing the future to make things better. Meng Dan (not enough information on his Way) is Fall. He records the history of the year, especially when things are starting to change for the worse and either and stagnate.
Ling Qi is Winter, who Ends the old and pits this to rest. She restarts the cycle to give new things room to grow. Gan Guangli is Spring, a guiding and preserving Buddha, who guards and protects the people and preserves them in harsh times until they have space to grow.
And then it loops back to Xia Lin....
