It worked successfully
In English, it’s quite common to say “It worked well.”.
In mandarin, There are many situations for “It worked well.”
For example:
1. It worked well without any disturbing. In mandarin, we should say : It worked smoothly.
2. It worked well and archived your goal. In mandarin, we should say: It worked successfully.
3. When you thought it was broken, but actually it worked well with the broken part. In mandarin, we should say: It’s still useful.
Here is a mistake of a student.

He wrote: This is the first time I did shopping online. It worked very well.
“Zhè shì wǒ dì yī cì zài wǎngshang mǎi dōngxi 这是我第一次在网上买东西. Hěn hǎo 很好.”
In mandarin, we should be: It worked smoothly “Hěn shùnlì 很顺利.“.Instead of : It’s good.”Hěn hǎo 很好.”
