Are they the same as the new rules? I haven't looked at them in detail yet.
I remember " / " being read as "slash", and in Chinese, it's pronounced "sila shi". There was also another one that I forgot.
~I rarely used to call in my zone code when crossing zones; I would just directly call in the zone number. However, most of the time, I was simply listening for instructions. Although this wasn't compliant with regulations, it was mainly because I rarely had opportunities to cross zones, and I also had a sense of侥幸 (luck/optimism). So, don't make the same mistake as me.
