Are there any historical conflicts or personal examples caused by poor Mandarin?

The people of Dongou call fire a tiger, and they say that fire is indistinguishable from a tiger. The country has no cultivation, but houses are covered with thatches, so there are many fires, and the people suffer from it. A Jia man from Haiyu came to the Jin Dynasty. He heard that there was a woman named Feng in Jin who was good at fighting tigers. However, there were no tigers in the town where Mrs. Feng lived, so she returned to Yu Dongoujun. Lord Dongou was overjoyed. He ordered his wife Jia Ren to travel to Jin with a horse of ten horses, two jade hubs, and fine brocade. When Feng Fu arrived, Lord Dongou ordered him to drive with his left hand, and welcomed her outside the country's gate. Tomorrow, there will be a fire in the city, and the people of the country will go to Feng Fu. Feng Fu rushes out from the country with her arms, asking for help but not getting it. The fire broke out in the palace, and the people of the country gathered around Feng's wife to follow the fire, and she was burned to death. So Jia people were offended by their presumption, but Feng's wife died without realizing it.

The following is the translation

Dongou, now the Wenling area of ??Wenzhou, Zhejiang, was called Dongou Kingdom in ancient times. The people of Dongou pronounce "fire" and "tiger" indistinctly. At that time, Dongou State did not know how to make pottery or smelt metal, and all houses were built with thatch roofs. Therefore, fires often occurred, and the people of Dongou were very distressed by this. Once, a businessman from the seaside of Dongou State went to Jin State to do business. He heard that there was a man named Feng Fu in Jin State who was good at hunting tigers. There were no tigers in the city where Feng Fu lived. After the businessman returned home, he told the king of Dongou about the incident. The king was very happy, prepared generous gifts, and appointed the businessman as a special envoy to invite Feng's wife to Jin. When Feng's wife arrived, the monarch left the seat on the left side of his car empty and went to greet her outside the city in person. They then drove into the city together and arranged for the hotel to be treated as an honored guest. The next day, there was a fire on the street. Someone ran to tell Feng Fu. Feng Fu rolled up her sleeves and waved her arms and followed her out, but she didn't see the tiger. At this time, the fire had approached the palace, and people pushed Feng Fu into the fire. As a result, Feng Fu was burned to death. So the businessman was punished for talking nonsense, but Mrs. Feng didn't know what happened until her death.

This is a very famous fable. If you search for Feng Fu, you will know that this person is the first tiger-fighting hero in Chinese history

This fable can show the necessity of the emergence of Mandarin and the importance of popularizing Mandarin. With the current increase in population mobility, the younger generation should learn Mandarin as soon as possible so that they can communicate with each other and avoid unnecessary trouble and misunderstandings.
