What's the difference between a dish and a plate?

Dish can be said to be a dish or a dish.

For example:

Now wash the dishes!

Can I have a Chinese dish?

Can I order a Chinese dish?

Where are the plates? You can only talk about it as a plate.

Using the example I used above can also be written as:

Now wash this plate!

Now wash the dishes!

The tray is like a formal high-end restaurant, serving food and tea. The waiter will drag it in with a tray for you.

This tray is called a tray!

I wonder if my explanation is transparent? Hehe v
