30 – The number of years since Shanghai’s economy was larger than Hong Kong’s. Not anymore, though: according to figures from Bloomberg this week, our fair city is US $17.6 billion richer than the southern powerhouse. But as Confucius said, mo’ money, mo’ problems… 

3.54 million – The total number of yuan taken in bribes by disgraced former Putuo district director Cai Zhiqiang and his lackey Yin Kunneng, as revealed in their court cases this week. Cai will serve 14 years, and Yin’s sentence is as yet undecided, although prosecutors are pushing for a minimum of 10 years. The pair obviously failed to read the rules on being corrupt. 

0 – The number of clues that Yao Ming has provided foro where he and his wife plan to have their baby girl, who is due in July. Netizens have been speculating that baby Yao will be born in America, and be ineligible to play basketball for China… a fate that appears to be a foregone conclusion should she be born here.   

-5 – The number of degrees Celsius that we luckless Shanghai folk had to endure for a period this week, along with a brief snowfall. Fear not, frozen friends, a high of 19 degrees is predicted for Friday.  

2000 (and growing fast) –  The membership of the Jing’an Elite Union, a new VIP club for white collar workers that's been particularly popular among migrant workers. The club offers all sorts of fun perks, including shopping discounts, a book club and… free psychological counselling.
