What is the origin of the sentence "Shandong scholar is half-finished"?

In Shandong dialect, the pronunciation of the part of Chinese characters used as phonetic symbols becomes too loud, otherwise you should be able to pronounce the words correctly by reading half of them.

There is a widespread saying that a scholar is too lazy to look up a word he doesn't know, or he is afraid of losing face. One trick is to read half a word. For example:? "Jing" reads "Guang", when encountering "Ke" reads "Ke", when encountering "Luo", and so on. However, this method is not so lucky for you. For example, the saved "Wan" does not pronounce "Exemption", while the wayward "Yi" does not pronounce "Blessing" but reads "Bi".

With the reform of Chinese characters, the pronunciation of phonetic notation has changed, and it no longer plays the role of phonetic notation. I made a joke in the middle of it. Now "a scholar can only read half" has become an irony for "a scholar" to read wrong words.
