(Old Factory Director) Pinyin is as follows:

Hanyu Pinyin lǎo chánɡ zhǎnɡ

Note: This does not involve soft tones, only tones.

The word "factory" originally had the third tone, but because the word "factory" is also the third tone, "factory" had to be changed to the second tone.

Ps: When spelling Pinyin, you should always pay attention to the following issues.

1) Front and back nasals should not be confused. Such as in and ing, en and eng, etc.

2) Flat tongue sounds and raised tongue sounds should not be confused. Such as zi and chi, si and shi, etc.

3) Tone symbols must not be marked in the wrong position. For example, the fourth tone of hui (hui) is mistakenly marked on the letter u, but it is actually marked on the letter i.

4) When dealing with tone-changed words such as "一不七八", mark them according to the original tone, and change the tone when reading. For example, definitely, "一" originally has one tone, but it needs to be pronounced as the second tone.
