Sometimes it is not easy to find the lost deer. For example, when grazing in the forest, some deer get lost by dragging behind. The grazing deer should be counted every day when they leave and return to the pasture, and it is easy for the deer to get lost on the way back and forth. Shepherds must actively call for the guidance of the deer in front, and herders should do a good job of defending and driving on both sides and rear. If you find a lost deer, you should report it in time so that you can find out and find out the reason for the loss. You can count deer when grazing, but it is best to count them at a narrow crossing. The herdsmen in charge of statistics stand in a higher position. In order to make accurate statistics, we should drive the deer slowly, don't shout loudly, and prevent the deer from spreading to both sides. When going out to graze and returning to pasture, it is easier to count near the gate of the fence. It's best to open a door and let the deer enter in a row. It is best to count three deer in a group, which can be fast and accurate.
