Ahh, I finally figure it out!!!
Design for Desire 360 video:
There are 5 elements contained in the video: Wine, coins, dragon, mercury particles, petal.
All of them represent attractive things.
Wine pouring over player heads, then crazy particles like mercury burst out, dragon flies away. Coins and petals dropping from the sky. Dragon means unreal but fantasy things, coins means wealth. They are symbols of desire.
Petals
Petals are based on a Buddhist legend: when Buddha and his students were meditating, some fairies passing by and dropped petals carelessly. Petals stick to students’ bodies, very hard to remove. However, no petals left on Buddha’s body. Students asked Buddha why, Buddha said because there’s nothing in your heart, nothing can affect you.
This story is used to tell people to decrease desire in Buddhist text.
