Surprise mail from China

Welcome back me! It's been a while since my last post, huh? Got tied up with work and it took me some time to adjust since I'd been working freelance for years before going back to an 8-hour job. In fact, I'm still adjusting until now but also trying to manage my time effectively so I can still do the things I love despite being busy with work.

One that I have started doing again is writing and swapping letters and postcards. Just sent a batch of postcards a couple of weeks ago and received a couple, too. It really makes me happy when I go home and see a not-so-empty mailbox.

These were in my mailbox yesterday:

Both are from Lirong Huang of China. In the envelope is a little note, some ephemera, a bank note and a coin, and a pop-up card. I loved everything, especially the pop-up card... it's so pretty, I just had to share it here...

It makes me want to attempt creating something similar but it's not yet time. Haha. By the way, 
I don't know if the symbol means anything, if it does, can you tell me on the comment section, please?

Hoping for more happy mail days!
