Hey fasteddie,
I am not asian, but my husband is chinese! I thought Mei Mei meant "pretty pretty" in chinese? I will have to ask him again.
I believe the Panda Bear here in San Diego at the zoo, is named Mei Mei, and she is quite famous around here! I have always liked that name and decided to name my little yorkie Mei Mei after Mimi (grandma) said 'No' to that name!! LOL
