How to explain the culture of China to foreign friends?

I once studied oral English with an American teacher. He always asks me to prepare a topic. In class, first of all, I will talk about the topics I have prepared. Then, discuss it by this topic. So I often introduce something with China characteristics.

Festivals in China: Festivals in China are generally closely related to eating, so I prepared the topic of festivals in China. Introduced what festivals to eat. For example, eat moon cakes in Mid-Autumn Festival, zongzi in Dragon Boat Festival and jiaozi in Spring Festival. On the one hand, it introduces the special festivals in China, and at the same time, it also introduces some special cuisines in China.

Chinese characters: I once told my teacher about China's Chinese characters. China's 5,000-year history of civilization is due to Chinese characters. Because there are many dialects in China, many dialects are almost incomprehensible to China people. But everyone uses the same words, which makes the decree better transmitted and better safeguards the rule of the country. Chinese characters are still one of the few ideographic characters in the world, and they are very efficient. For example, the English word silicosis is more than 40 letters. Most Americans don't know each other. Chinese only needs three words' silicosis'. Even people who don't understand this disease can probably know what this disease is about when they see these three words.

BYD's new energy vehicles: As a' Difen', I certainly want to introduce some new energy vehicles of BYD. I introduced to the teacher that BYD's new energy vehicle can accelerate in 4.9 seconds. Oil and electricity can be mixed. Most importantly, it's cheap. It is several times cheaper than Tesla. Let the teacher feel the black technology in China. But the teacher said he was a little worried about hybrid cars, and he preferred pure electric cars.

Food in China: Food must be introduced, but I don't know much about it. It's all about Baidu. For example, Anhui cuisine is mainly sauced, Hunan cuisine is mainly spicy, and Shanghai cuisine is sweeter. Actually, I haven't eaten either. It's purely scripted. But the teacher is very interested. His favorite is hot pot.

Foreigners spit: I once saw a foreigner's experience of living in China on the Internet. Some of them spit, and I like to explain these phenomena to teachers through this topic. For example, if foreigners can't stand squatting in China, I will explain that squatting is hygienic and convenient, except that squatting is a little tired. There are really no shortcomings. Also, people in China like to take photos with foreigners. I say it's because of our enthusiasm in China and so on.

More interestingly, once, I asked my teacher to explain the ten principles of mystery novels. I told my teacher the ten reasoning principles of Baidu English. The teacher didn't understand. Later, I showed him the original text, but I couldn't understand it either. I wonder if there is classical Chinese in English? The ten principles of reasoning in Conan Doyle's era are beyond the comprehension of modern Americans. Of course, it has nothing to do with China culture, but it feels very interesting. Let's talk about it
