Usage of 地 part two

In the previous class, we talked about the usage of this character 地 when it makes the dì sound and it has the meaning like earth, ground, or region.
In this video, we will cover the basic usage of this character when it makes de sound, and it becomes a structural particle.
Since 的 and  地 has the same sound, even many Chinese people get confused about them. They may just say:"It's not important. I don't care. " And I often see people use them in the wrong place. Most time people just use 的 for everything.
But if you are learning Chinese seriously, master the usage of these two characters will be very helpful for your reading and writing.
