Parental love or child abuse

There should be a line demarcating where parents' expression of love ends and child molestation begins. Besides, acts of affection should be within the confines of social norms, says an article in Southern Metropolis Daily. Excerpts:

A person recently filmed a man kissing a little girl "improperly" on a bus in Zhuhai, Guangdong province. After being posted online, the video created a public controversy, with many netizens saying the man's action constituted child molestation. But the Zhuhai public security authorities announced on Dec 7 that the man in the video is the 3-year-old girl's father and there is nothing to suggest his behavior was inappropriate.

The man in video, surnamed Chen, has been quoted as having said that he was trying to cheer up his edgy daughter.
