Today I met with... @BH7CNC_Jack I went to the card center and found some interesting cards that were made. I'll send them over for everyone to share.
First, take a quick look at how many people each person is sorting in an afternoon.


Okay, let's give it two seconds... and now, I'd like to move on to the main topic.
1# This piece of paper appears to have been torn directly from a card.

2# Pixel art style, cute.

3# Some double-page designs (which seem to be quite expensive)






4# At first glance, I thought it was a French-made bird feeder.

5# This one also looks like it was made by himself, and he only created a white card with the call sign. The rest of the information (including QSL information and address) were affixed using self-adhesive labels.
6# This is the oldest QSL card I've found so far (not as good as the first BS7H expedition I found last year)

7# First time seeing a BL7 QSL card.

I checked qrz.com and found that BL7IA's address is in Shenzhen, and BL7JJ is managed by a Hong Kong-based organization called "Hong Kong Friends of Taiwan".
The BL7 prefix appears to be the call sign used by Hong Kong HAMs when setting up stations on mainland China. If anyone with knowledge of HAM radio can provide some information, it would be appreciated.

In fact, there are also some quite peculiar cards, such as those that are too soft to hold, too hard to hold, or too thin to see details in the camera. Here, I will only describe them.
Overall, this time, the Beijing station received more QSL cards from European countries, accounting for 70%. Those who contacted EU stations will have good luck.
So I spent an afternoon looking for them, and I managed to find a few cards.

It's either running at a low capacity or completely shut down.
