I remember a few decades ago, there was a way to write the word "Zhang", especially like the "biography" of regular script. Who can tell me how to write it and explain its general usage? Thank you.

In China's calligraphy, there are many special ways of writing, one of which is called "cursive script", which is often used to write some specific occasions, such as:

1. Official Document: In ancient China, cursive script was widely used in official documents and letters. This is because cursive writing is faster, and its special stroke structure can effectively convey the importance and authority of the document.

2. Calligraphy works: As an art form of calligraphy, cursive script is widely used in the creation of calligraphy works. Artists express their feelings and thoughts through the stroke structure and line flow of cursive script.

3. Folk Celebrations: In some traditional festivals and celebrations in China, people also use cursive script to decorate venues and perform props. For example, in some Spring Festival celebrations, people will write couplets and blessings in grass to express the festive atmosphere of the festival.

As for the cursive script of the word "Zhang" you mentioned, it is like this:

1. Write the left part first: write down the word "bow" first, which is common in cursive scripts and has a simple structure.

2. Write the right half again: In cursive script, the right half of the word "Zhang" is generally written as "beside the vertical knife" (Xian), and this part needs to pay attention to the stroke structure and position.

The above is a common cursive writing. It is worth noting that cursive writing is very diverse, so the specific writing may be different because of different regions, years and writers' personal styles. Want to know more about the writing style and cultural background of cursive script, I suggest to find a professional calligraphy teacher to learn.
