**Why name it Qi?** Qi was derived from the pinyin of the Chinese character "气", which means "air" in English. I wanted this language to be quick and lightweight, as well as fully transparent, just like air!

- Qi is <ins>Chinese-based</ins>. Us English-speaking people don't often take for granted the fact that the programming languages we learn are all based on native tongues we're already fluent in. A native English speaker can reasonably infer what a piece of Python code does just from reading the keywords ("if", "int", "while", etc.). Making this language foreign-based allows programming to be more accessible to more people around the globe.

Booleans can only have 2 values: 真 (true) or 假 (false). The value expresses the validity of a condition.

Constructors are called on initialization of a new object in a class. This is usually where class properties are declared and initialized. You are allowed to pass custom parameters into the constructor.

变量 式 = 树（3）

To set a property of an object, do the same thing that you would do with a normal variable using a ```=``` operator.

The keyword ```这``` is used to specify that the variable you are accessing or modifying belongs to the enclosing class. This is especially useful in constructors, where the compiler may not be able to differentiate between the constructor parameter and the class property.

When a class inherits from a superclass, all of the parent class's methods and properties are "passed down" to the child class.

The keyword ```超``` is used within child classes to execute methods that they inherited from parent classes. This is useful when you are trying to execute a method when you want to access the superclass method being overridden.

It is often useful to execute different pieces of code based on certain conditions. You might want to run an extra piece of code when an error occurs, or to display a message when a value becomes too high or too low. To do this, you make parts of your code conditional. In its simplest form, the ```如果``` statement has a single if condition. It executes a set of statements only if that condition is true:

如果（真）「

」

如果（假）「

」

The ```如果``` statement can provide an alternative set of statements, known as an else clause, for situations when the if condition is false. These statements are indicated by the ```否则``` keyword:

如果（假）「

」否则「

」

To chain extra conditions after the previous ones fail, you can combine the else clause with the if condition, forming ```否则 如果```.
