This kind of calligraphy and painting such as "God rewards those who work hard" cannot be pasted crookedly. Because this picture is posted crookedly on the wall, it means that the motivation for studying and the day's entertainment are somewhat abnormal, and the images of Shunyi and the magnetic field induced by objects are also incorrect. This leads to the decline of luck. It is proposed to remove it and re-paste it in order to bring good luck.
