However, there is a little-known secret behind Qianlong's "high yield" According to the Grand View of unofficial history in Qing Dynasty, Qianlong's poems were "not written at the beginning", or improvised dictation, or calligraphy was called "poetic films", which were copied by courtiers and made into imperial poems. To put it bluntly, when his poetry was in full swing, he pretended to be vague and confused, and the words he wrote were confusing. At that time, whether he could "record" a masterpiece became the standard for ministers to favor and promote. Once, a university student and another minister, Liang, were summoned at the same time, and this poem was suddenly sung. Liang was at a loss after listening, but after listening, he "retired from the room and recorded it, but it was only a word or two." Liang didn't understand the mystery, and sighed, so he was "amazing." The poems concocted by this flattering minister are at best plain in rhyme and correct in writing. Because of this, tens of thousands of "imperial poems" written by Gan Long have been handed down to this day.
