On weekends, Dahua drove his wife to Jinshanzui fishing village in the suburbs of Shanghai to taste seafood. Before leaving, he deliberately turned on the navigation on his mobile phone. Unexpectedly, he was a novice. At a three-way intersection, the navigation was a few beats slow, and the car passed the ramp and entered another highway. Dahua asked his wife to help, but unexpectedly turned off the navigation after fussing with it, so he had no choice but to drive all the way. By the time the navigation was normal, the car was almost approaching Ningbo . The wife was angry and annoyed: "Thankfully you are still a teacher, and you can still drive the wrong way when following the navigation. How do you usually teach students?"

Dahua said plausibly: "Wife, I teach Chinese, and I can't figure out the east, west, north, and south. , It’s normal. Besides, it’s not bad to taste the seafood and see the scenery on the way.” My wife didn’t know what to say after hearing this.

In a blink of an eye, the Golden Week of National Day is here. The couple agreed to drive to the surrounding scenic spots. Dahua confidently said to his wife: "The navigation was unreliable last time. Look, I won't drive the wrong way without the navigation." !" Sure enough, after a few days of driving, the journey was smooth and I didn't go the wrong way. The wife was very surprised, but Dahua smiled proudly: "What's so strange about this? Our amateur culture training school has been short of geography teachers recently, so I switched to geography. Now, even the stars in the sky, I You know where it is, let alone these small underground roads!”

After a while, my wife had to go to the city library for a meeting, which was not far away, and Dahua insisted on driving her. My wife got in the car and lowered her head to play with her mobile phone. After a while, she heard Dahua honking his horn desperately. When his wife looked up, she saw the car driving through a residential area and was blocked by a truck. My wife couldn't laugh or cry: "Why do we have to drive into a residential area to go to the library?"

Dahua rolled his eyes at her: "The straight line between two points is the shortest, which saves time and fuel. Why take a long way?" He said, He smiled secretly: "Tell you, I recently switched to teaching mathematics! I understand this!"
