This apparently just became the appropriate thread after you've changed the thread title from "
Some Questions about the Z-9" to "
Z-9 in PLA service" within the last 30 minutes or so.
The thread was opened 15 years ago by a user to ask some general questions about the Z-9, thus its original title "
Some Questions about the Z-9". It had served its purpose and remained dormant for almost 7 years until
@xyqq revived it so he could insist on spamming the forum with low-quality and boring images.
By the way, reviving an old thread goes against the current forum rule that states "If a thread is old, or closed, and if new material comes up, open a new thread under the same name but add a 'II' or next available Roman Numeral to the thread title". And this is without even considering the fact that as it originally stood, this thread was completely inappropriate for the purpose of a dedicated Z-9 thread.
