There's a discussion forum on the Harolcq Ham Community website called "DX Communication." It ostensibly covers topics like DX, expeditions, island communications, contests, awards, SWL (Shortwave Listening), propagation, FT8, RTTY, and PSK31. However, most of the posts are about amateur radio enthusiasts sharing their contest results, describing the contest environment, and exchanging tips after each competition. I've gained a lot of valuable experience through these types of posts. Personally, I think it would be beneficial to create a "Contest Zone." Within this zone, contests could be categorized by frequency band (e.g., shortwave, UV), and then tagged with relevant keywords (e.g., wapc, iaru, cqww, wpx, uvcc, dxcc). The tags could be selected or filled in. For example, if I were to write a post about wapc, I would go to the Contest Zone, click "submit," and the system would select the frequency band "shortwave" and the tag "wapc." Then, I would write the post. I believe this would help new participants gain some basic experience within the community.
Of course, this is just a proposal, and whether it will be successful in raising the level of amateur competitions within China remains to be seen.
