官方：原山东泰山外援贾德松加盟巴西球队葡萄牙人RJ（官宣：前山东泰山外援贾德松签约巴西葡萄牙人RJ）

Providing transfer info

I need to present neutral information: Portuguesa-RJ competes in the Campeonato Carioca, and it seems like this transfer could be a free move, although the contract length is unknown. I can check if the user would like an official source link. I can also share background on the club and league, along with information about Jadson's time at Shandong Taishan, including his appearances and contributions. I'll be cautious to avoid misstating any of his stats. It might be safer to generalize, so I could say something like "在泰山效力期间帮助球队夺冠."Confirming transfer details

I want to create a concise confirmation and include some background context. I can offer to gather additional details like contract specifics, debut date, and past stats. I should also check if the user wants a draft or a social media post. It seems a neutral presentation in Chinese would work well. I plan to mention Portuguesa-RJ: “里约州甲级（卡里奥卡锦标）,” and I’ll confirm that 贾德松 is a 中后卫—he's indeed a defender for the team. Time to produce that!
