Cedar introduction: When Liang Shiqiu was living in Qingdao, he once accidentally mentioned that he hoped to plant some trees in the courtyard, but he did not expect that the landlord would bring two carts of tree seedlings not long after. So my husband planted six cherry blossom trees, four apple trees, two crabapple trees, and a cedar tree in the courtyard. As time goes by, many of the trees in the courtyard have disappeared. Only one cedar still stands tall and tall to commemorate the kindness of Mr. Zang.
