Ru Mao drinks blood. About 700,000 to 200,000 years ago, the people of Beijing already knew how to use natural fire, and 30,000 years ago, the people of the cave at the top of the mountain mastered the technology of artificial fire, and they used fire to grill food, thus changing the situation of "Ru Mao drinking blood".
In winter, they live in the camp cave, and in the summer, they live in the trough nest.
7,000 years ago, the Hemudu people were already able to build dry-stilted wooden houses, and 5,600 years ago, the Banpo people were already able to build round-roofed semi-crypt houses, thus changing the situation of "living in caves in winter and trough nests in summer."
There is no linen silk, and the skin of the feathers is clothed.
A bone needle was unearthed at the 30,000-year-old cave man site, proving that people were able to connect animal skins to cover their bodies. The world's earliest textile tools unearthed from the Hemudu site 6,000 years ago and the spinning wheel unearthed from the Banpo site from 5,000 or 6,000 years ago all prove that the people at that time already knew how to weave, thus changing the situation of "no hemp silk, no clothing and feather skin".

1) Low latitude is the area within the Tropic of Cancer (degree N) and the Tropic of Cancer (degree S), which are called low latitudes. Look at the places in which they are filled!
2) What direction is point A in point C: You only need to draw a cross "ten" at point C, and point C should be in the center of the figure "ten". At this time, the cross is north, south below, west on the left, and east on the right.
You look at where point A is on the cross, and if it's in the lower left corner, it's southwest. In the bottom right corner is:
Southeast. In the upper left corner: Northwest.
In the upper right corner: northeast.

And so on: in what direction is point e at point B: you just need to be at point B.
Just look at where point e is at point b (3) The meridian is vertical, and the latitude is horizontal. You can see where those points are at the intersection of two latitude and longitude lines, just fill in the degrees of those two lines!
