The methods of creatingby which Chinese characters were created (1)

When I first read your original title, I thought the post would be about how people write Chinese characters nowadays. Changing to past tense clarifies this a bit, although I would suggest something simpler, such as “How Chinese Characters were Created” or “The Sources of Chinese Characters.”

I thought perhaps I could write something to show you guys how I learned those characters as a mother tongunative speaker of Chinese.

Your original wording means that the characters are your mother tongue —you learned to read & write before you learned to speak.

{At the beginning of m, I was taught | My first step, I wasacher taught me} that there are six sources of characters.

{At the beginning, I was taught | My first teacher taught me} that there are six sources of characters.

Four of them weare the ways ofmethods used by our ancestors into creatinge Chinese characters, and the restother two weare the ways of usingmethods used to extepand their meanings.

Four of them are methods used by our ancestors to create Chinese characters, and the other two are methods used to expand their meaning.

I will explain them one by one inover the next six days.

“In” isn’t wrong, but “over” sounds more natural to me.

Theseis potteries arey is the earliest writing medium that we can see currently.

Here are several typical pictographic characters: 日 (sun)、田, 田 (field)、人, 人 (person)、口, 口 (mouth)、山, 山 (mountain)和门 and 门 (door).

I just corrected punctuation and spacing:

(Even) After thousands of years of development and change, we can still observediscern a picture fromin each of these Chinese characters.

• Adding “even” emphasizes how amazing this is.
• “Observe” is fine, but I thought you might like “discern.” 😀
• “From” seems wrong to me.

At the beginning of my first step, I was taught that there are six sources of characters.

You could simply say "At the beginning/start, ..." or "The first step that I was taught...". It's a little redundant to use both "beginning" and "first step".

Four of them were the ways of our ancestors in creaancient methods of creating (or writing), and the restmaining two were the ways of using tomethods for extending the meanings (of the characters).

I will explain them one by one in the next (or following) six days.

The source of the original characters is pictures.

Or: "The original characters are based on pictures."

According to the current archaeological discoveries, the origin of Chinese characters dates back approximately 6,000 years.
