A WOMAN AND HER THREE CHILDREN died in a fire at their home in Hangzhou, East China's Zhejiang province, on Thursday. The nanny was subsequently arrested on suspicion of arson. Beijing News commented on Tuesday:

People are naturally asking why the nanny would start the blaze in the high-end residence in Hangzhou, especially since she was reportedly treated well by the family. Apart from a decent salary, the couple reportedly loaned her 100,000 yuan ($14,870) when she told them she needed the money to purchase a property in her hometown.

Some assume the couple's total trust in the nanny cost four lives, while some urged households to think twice before hiring a nanny. But the tragedy in Hangzhou, if it proves to be the act of the nanny, was because of her psychological issues not her job.
