I recently called to inquire, and I was asked to provide records of amateur radio competitions and records of transmissions from visitors outside the province. The required materials are similar to those that need to be provided by individuals with a license and transmissions exceeding 15W, as specified by the Ministry of Industry and Information Technology.
Last month, I made a few mistakes during the CQWW CW competition, but I still managed to complete the contest and have a record.
Recently, I've been in Ningbo, and I'm planning to socialize there. Once I find a friendly amateur radio operator, I'll also start logging contacts from other provinces.
