Sending rain to Jiang (Song Jiang) is useless to know many stars (Wu Yong). Does the author of Water Margin hint at the ending?

Yes, the names of many characters in the Water Margin have certain meanings, implying the fate of the characters.

Song Jiang, nicknamed Timely Rain, often saves people from danger. He is a hero, surrounded by many heroes, but in the end, Song Jiang himself ruined the future of himself and his brothers. Ruined their possible future.

Wu Yong, nicknamed "Zhi Duo Xing", is resourceful and has many golden ideas, which are also very useful. Unfortunately, it's useless to follow the wrong boss and the wrong direction. At that time, if you follow Fang La, you might not call Wu Yong, but you can call him Wu Tian. Ha ha.
