【答案】Dear Mayor，
I'm Li Hua，a student in Grade Two.Since our city is struggling for National Civilized City，as a responsible citizen，I think there is something to be improved.
As we can see，shared bikes，increasingly popular in our city，are often parked at random，which damages the image of our city.Besides，the traffic issue is still a hard nut to crack because some drivers and pedestrians usually ignore the traffic rules，thus causing many accidents.
My suggestions are as follows.Firstly，the government should produce stricter rules to regulate the management of bike-sharing system.Secondly，campaigns should be launched to remind the public to obey the public rules.
I would appreciate it if you could take my suggestions into serious account.
                                                                                                       Yours Sincerely，
                                                                                                       Li Hua
