在圖書館隨手拿八本中文書一本英文書翻了兩個小時，水準最高的是這個台灣人朱敬一博士寫的，經濟學教授，還擔任過台灣駐WTO大使，據說此人什麼學問都懂一點，還是美食家，並會自己弄，不過我最服他是花了十秒鐘就學會蝶泳，我在台灣住在環亞假日，有戶外泳池，健身房兩員工教我蝶泳幾次我就是學不會。 https://t.co/sjJDt9zTEA

It seems that the post does not relate to a maintenance report feedback to public flat house. The post simply says "wto" and does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to this category.
