Food carts, especially those carrying yellow fishballs, are an iconic sight on Hong Kong's streets.
But Monday they were the catalyst for a clash between the police and the vendors that left dozens injured and many arrested.
The riot started simply enough with the police ticketing undocumented street stalls that were set up in the Mong Kok area of the city for the Lunar New Year celebration.
The chaos was almost immediately dubbed as the "Fishball Revolution" by social media.
In mainland China, which has a complicated relationship with Hong Kong to say the least, there have been 4 major types of reactions to the clashes among users on Weibo:
1. "Blame democracy"
2. Condescending comparisons with mainland China.
3. Conspiracy theories against the U.S. — again.
4. "Holding a different voice is dangerous."
They were soon pelted with comments like this one.
But the lighthearted takes that bubbled up on Weibo ignored the the significance of the Umbrella Movement and the follow-up that played out on Monday.
