PC has been away for a month. Because of work, PC has to run out of the country often. This time he went to the small town in the north for more than four years. Four years have made me go from an inexperienced little girl to a mature woman. In this famous multinational company, I have also gone from a small administrative assistant to a training manager in charge of consumption training in China. The busy work of us both flew around the world. Only half of the time we can stay together in a year.
