To make the case study meaningful
I will have to disclose lots of details, which I don't feel comfortable -- I never like to volunteer info. It's tricky to handle the balance between confidentiality and transparency (that thing itself is highly political:). If I do disclose a lot of things, I'll just walk away, let time wash them out, and I may be back with another ID later:).
As for the real case, I've found solutions -- they are going to work, but time is too pressing, there are only three months left, and I planned to go back to China for Christmas and New Year, and planned a trip to Hainan for pleasure (personal happiness, I love Hainan quite a bit).
