I saw those comments one after another online and I translate them here:

1, Core Hu held Fat Kim No.2 indicating that even death can’t separate Heaven Dynasty and North Korea.
2, Held a sucker (衰仔) giving money everyday, **.
3, The socialist camp are gradually diminishing. No wonder the President held Fat Kim tightly.

Note:
1, Core Hu refers to President Hu. Since the Chinese central TV (CCTV) and other Chinese official media like to refer President Hu to a leadership core of China.
2, Some Chinese people refer Kim Jong-Il to Fat No. 2, his father Fat No. 1, his son Fat No. 3.
3, Some Chinese people refer Heaven Dynasty to Chinese government or China ironically.

I only saw one post saying that he/she’s happy for Kim Jong-Il’s visit:

I like Grandpa Kim. Since he came to our school, we had a holiday.
