1. The job positioning and classification are unclear, and I often feel at a loss.

2. Some people have bad attitudes. If you win their favor, everything is fine; if you don't, they immediately report on you behind your back. If you don't obey, they will ultimately leave you with no job.

3. Having abilities is useless here; there is no room for you to perform. Professional expertise counts for nothing. Everything has to follow the old methods, leaving you unable to learn anything and turning learning into being a controlled puppet.

4. There is nowhere to eat nearby, so you have to bring your own lunch. This can help you hone your cooking skills.

Before joining, everything seems wonderful; after joining, everything suddenly becomes clear.

Perfect, with no shortcomings.
