Meanwhile, Gao Yu pointed out to Ma that one way to enrich his state was to sell tea to territory directly under Later Liang control. Thereafter, Ma requested and received permission from Emperor Taizu to establish tea trade offices at Bian Prefecture (汴州, in modern Kaifeng), Jiangling, Xiang Prefecture (襄州, in modern Xiangyang, Hubei), Tang Prefecture (唐州, in modern Zhumadian), Ying (郢州, in modern Jingmen, Hubei), and Fù Prefecture (復州, in modern Tianmen, Hubei), for the purpose of selling Chu tea and purchasing silk and horses, with part of the tea offered to the Later Liang imperial government as tribute. It was said that Chu began to be enriched after this trade began. Later in the year, when Gao Jixing tried to cut off this trade by stationing forces at Hankou (漢口, in modern Wuhan), Ma sent Xu to attack him, and Gao Jixing, in fear, sought peace. Ma also sent Lü Shizhou () to attack the territory of Liu Yin the military governor of Qinghai Circuit (清海, headquartered in modern Guangzhou, Guangdong), capturing Zhao (昭州, in modern Guilin), He (賀州, in modern Hezhou, Guangxi), Wu (梧州, in modern Wuzhou, Guangxi), Meng (蒙州, in modern Wuzhou), Gong (龔州, in modern Guigang, Guangxi), and Fù (富州, in modern Hezhou, note different character than the prefecture in Tianmen) Prefectures from Liu Yin.
