As an example, if a potential buyer asks a question on an auction, Cai will answer in as much detail as he can as soon as he can. He also goes onto popular electronics community sites Mobile01 and Yahoo! Knowledge (a Taiwanese site similar to Yahoo! Answers) to answer any and all kinds of computer questions, adding a link to his store to his posts.
舉例來說，當買家在拍賣網頁的「問與答」提出問題，他總是儘可能在最短時間內詳細回覆；他還會主動上「Mobile01」等 3C 買家的社群網站、甚至是 Yahoo ! 奇摩的「知識＋」，為各種天南地北的電腦問題解惑，再貼上自己賣場的連結。
