Some streets are so busy, you should alert your eyes when there are some strangers that asking for something. But one thing for sure is very mysterious to some people. Do you noticed the "Ped Xing" street signs along the major roads? Why the name of sign is "Ped Xing" but there's no street crossing across them. Other man said that it kinda name of a Chinese National. But all of these opinions are not true. Ped Xing is a short term for Pedestrian Crossing.
(Ped Xing is not one of the names of Chinese historical figures, it simply means a shortened pedestrian crossing sign.)***
