First, the question is to ask and answer, and the answer is outside the question.
For example:
"Ask how sad you are? Just like a river flowing eastward. " -Li Yu's Young Beauty
"Where to wake up tonight? Yang Liuan and Xiaofeng are dying. " -Liu Yong's "Yulinling"
"But who among them cried the most? ? This Jiujiang official. My blue sleeves are wet. " -Bai Juyi's Pipa Trip
"What can you hear here in the morning and evening? ? The cuckoo bleeds, the ape whimpers. " -Bai Juyi's Pipa Trip
"Of course there are folk songs and bagpipes in the village? It's hard to hear when you are dumb. " -Bai Juyi's Pipa Tour
"Where is the emperor in the cabinet today? The Yangtze River flows by itself. " -Wang Bo's "Wang Tengge"
Second, rhetorical question is a question with no answer, and the answer lies in the question.
For example:
Oh, how can I bow and scrape to those people with high status and important positions? They never want to be seen with a sincere face. -Li Bai's "Climbing Mount Tianmu in a Dream"
"Who can ask: Is Lian Po old enough to eat?" -Xin Qiji's "Never Meet Le Jingkou Gubeiting Nostalgia"
"If you want to send a colored note and a ruler, where do you know?" -Banquet "Recent Love"
"Yellow flowers are all over the ground, withered and damaged. Who can pick it now? " -Li Qingzhao's Slow Voice
Third, because rhetorical questions and rhetorical questions ask no doubt, sometimes there is no question mark at the end of a sentence.
For example:
"Read the red medicine by the bridge, and know who you are born for every year!" -Jiang Kui's "Yangzhou Slow"
