NOTES; Here the date we used to show when it is one of twenty-four solar periods is not accurate. Please refer to a Chinese lunar year calendar to get the exact time in its special system. The beginning and ending of each periods are so accurate that hour and minute are used.
1 - 1 - 2. Yue Jiang
Yue Jiang means sun. The earth runs along its own route with sun as the center point. In the same time, the sun runs along its own route if we regard earth as the reference object. In ancient China, people divided the running route of sun into 12 partition, each has a name. In fact, Yue Jiang is used to describe the complicated movements of rotation and revolution of earth. In ancient China, people prefer to use 12 Earthly Branches to describe the 12 partitions the sun runs into. So, we have the following form.

1 - 1 - 3. Heavenly Disc and Earthly Disc
 In LiuRen, the Earthly Disc always remains in the solid form, without any changes. It is presented with 12 Earthly Branches as follows.
Earthly Disc remains motionless, quiet, free of any changes. Yet, the Heavenly Disc always remains active and turns around Earthly Disc from outside even both of them can be presented with this same disc.
For example, soon after Yu Shui (TFSP02) one person comes for a divination at the time of  Wu (11:00AM - 1:00PM). By looking for the above form we know Yue Jiang is Hai (), then we should turn around the Heavenly Disc (same as Earthly Disc) clockwise to make the Hai stop at the Wu of Earthly Disc. If the person comes at the time of You (). Then we should turn around the Heavenly Disc around clockwise to make the Hai () of Heavenly Disc to stop at the You () of Earthly Disc. In such way we first learn the method of how to turn the Heavenly Disc. In fact, in LiuRen, most of the time we don't show up the Earthly Disc, just present the Heavenly Disc.
So, for the example of soon after Yu Shui (TFSP02) one person comes for a divination at the time of Wu (11:00AM - 1:00PM), we get the following Heavenly Disc:
