做事欺骗上司同时隐瞒同级和下属to cheat one's superiors and conceal from one's subordinates

• 如今谁又敢保证一些地方政府不再次作出那种欺上瞒下的事情呢？

  Now, who would dare to guarantee that some regional governments are not again cheating their superiors and concealing things from their subordinates?

• 对着百姓光是承诺不兑现，弄虚作假欺上瞒下。

  Towards ordinary people, one merely makes undertakings that are not made reality. One commits fraud, cheats one's superiors and conceals it from one's subordinates.
