Guo HaiPing made up her mind to buy a house as soon as she had enough money for the down payment, and ever since she graduated from university she has been living in Shanghai. But after looking at one house after another, none of them satisfied her. So HaiPing lived with her husband Su Chun in a rented room of only more than ten square meters for five years. From their courtship, to marriage, to the birth of their daughter RanRan, all happened in this small room. The arrival of a child was already making the couple very busy, and with the added help of grandmother, the space became even more crowded. HaiPing had no choice but to let her mother take RanRan back to their hometown to take care of her, while she immediately returned to work, continuing to save money to buy a house. After all, a daughter is flesh of one's flesh, and HaiPing's longing for RanRan grew day by day. In order to save money, she economized on food and clothing, even limiting the time she spent on long-distance calls and how often she returned home, but the worry in her heart could not be restricted. Guo HaiPing endured being separated from RanRan for nearly three years, and these three years were very difficult as she saved every penny.
