The standard watch is the oldest timer in China, which uses the length of the sun's projection to judge the time. It consists of two parts, one is the benchmark or stone pillar for measuring the shadow of the sun standing upright on the flat ground, which is called a table.
The other part is a rigid board called Gui, which is used to measure the length of surface shadow in the direction of due south and due north. The shadow of the sun can be used to represent time here, so it is reasonable to use "yin", "minute" and "inch" to represent time.
clocks and watches
Before mechanical clocks were introduced into China, sundials were the most commonly used timepieces. A sundial is mainly composed of hands and a surface engraved with lines. When the sun moves in the sky, the projection of the hands will move on the surface like the hands of a clock, so it can be used to indicate time.

Dials and sundials use the shadow of the sun to calculate time, but they lose their function when it rains or it gets dark. As a result, a water clock that can time day and night came into being, which is seal cutting.
Notched structure
The clepsydra consists of a clepsydra and a ruler. The clepsydra is used to drain or hold water. The former is called drainage clepsydra and the latter is called water receiving clepsydra. This ruler is used for timing. When in use, it is placed in a pot and moves up and down with the change of water level in the pot.
In addition to the master timer mentioned above
There are also some simple and convenient timing methods.
For example, in classical novels, it is often written that "the time of one wick of incense".
So how long does it take to burn incense?
A wick and a pot of wine.
Because many products.
In fact, due to the influence of many factors, such as environment, wind power, the length of incense, the dryness and wetness of spices, the burning time of a wick is not exactly the same, usually about half an hour, that is, one hour.

In ancient times, in addition to using a wick to time, you can also use a plate of incense, a stove incense, a cup of tea, a pot of wine and a meal to time. All right, let's talk about the time tomorrow.
