Tao Tie Ji means a festival for the Dragon King's son, Tao Tie and has more to do with chapter one than the remaining of the story.
The first 4 chapters show that the book doesn't have a definite plot, but centres on the two brothers, Kui Long and Tao Tie. They're sons from this guy called the Dragon King who is probably a deity, which makes the brothers deities too. They are usually referred to as Gods by villagers in the story.
I love the story so far.. the love stories in this manhua have been tragic so far, but it also shows how beautiful the romance is, which makes it so heart-warming and nice to read. The artwork is good as well.. bit sketchy at times, but still OK.
Edit: Okay I finished reading the raws. The later chapters will introduce the Dragon King briefly and the rest of the brothers. This family is like the Emperor Jade's family. They are royal deities and live in a palace in the deity-world. Tao Tie is the 5th son, who has another twin brother. And Kui Long is the youngest son, who is actually a half-blood.
The stories are cute and there are a lot more potential for more story-telling because all the brothers are bishounen, and each of them have their own character (which is pretty stereotypical - ie, the oldest is the most sensible, the second son is flake who disappears every few years just for fun chasing some shiny, etc.). However, there are only two volumes in this series, which is a pity.
It was fun reading them - recommended!
