Quest for Piles

Although I am not a posthumous child, I have lived for twenty-five years but have never met my biological father. My mother has always worked hard to raise me. Now that I have finally graduated from college, I am thinking about working hard so that my mother can live a good life for a few days. Who would have thought that I would suddenly receive the bad news of my mother's death~~~My mother had always been in good health, so how could she suddenly pass away at the age of less than fifty? In addition to my grief, I felt extremely wandering and helpless~~What made me even more anxious was that when I was sorting out my mother's belongings, I discovered a "treasure map" clearly written by my father, which clearly marked the time, place and purpose of his planned trip~~~
