When the warlord Sun Quan was nominally serving as the Administrator (太守) of Kuaiji Commandery, Luo Tong, then 19 years old, was appointed as the Chancellor of Wucheng County (烏程縣; south of present-day Huzhou, Zhejiang), which had over 10,000 residents. He performed well in office and received praise from Sun Quan, who promoted him to an Officer of Merit (功曹) and acting Cavalry Commandant (騎都尉). He married the daughter of Sun Quan's cousin, Sun Fu.(孫權以將軍領會稽太守，統年二十，試為烏程相，民戶過萬，咸歎其惠理。權嘉之，召為功曹，行騎都尉，妻以從兄輔女。) Sanguozhi vol. 57. Luo Tong was known for being very diligent in examining the state of affairs in his jurisdiction. Whenever he encountered important issues that required action, he would attempt to resolve them within the day itself. He also advised Sun Quan to give greater attention to talented and virtuous people, so as to attract them to serve him. He suggested that Sun Quan meet the guests individually (instead of in groups) and hold private conversations with them to understand them better and make them feel appreciated and grateful to him. Sun Quan accepted Luo Tong's advice.(統志在補察，苟所聞見，夕不待旦。常勸權以尊賢接士，勤求損益，饗賜之日，可人人別進，問其燥濕，加以密意，誘諭使言，察其志趣，令皆感恩戴義，懷欲報之心。權納用焉。) Sanguozhi vol. 57. Luo Tong was appointed as "General of the Household Who Builds Loyalty" (建忠中郎將) and was placed in charge of 3,000 troops. He was placed in command of Ling Tong's unit after Ling died.(出為建忠中郎將，領武射吏三千人。及凌統死，復領其兵。) Sanguozhi vol. 57.
