I want to know the answer to the following question:
What was the minimum hourly wage in Sichuan on December 28, 2007?
All the background I'm provided with is that "The monthly minimum wage went up from 400 to 450 yuan, with a minimum of 4.9 yuan per hour for part-time work, effective 26 December 2007.". Is that enough to answer the question?
Answer: yes
