My friend was at Changi Airport Terminal 1 Gate C19 when he saw this PRC lady tourist eating her biscuits while seated on the lounge chair. To his surprise, after eating her biscuits, this lady cleaned up the biscuit crumbs that had fallen onto the chair and disposed the mess nicely in a litter bin nearby.
He was truly impressed by this Chinese lady's act of civic mindedness. He shared this because usually news about PRC Chinese is negative and thought this is a breath of fresh air and worthy of praise.
Once again kudos to this PRC lady for showing Singaporeans the other better side of Mainland Chinese.
