Zhao Ming did not mention in his letter to Zhao Zhongyu that Zhao Hanzhang was planning to buy a colt; he only stated that Zhao's Fortress needed the strength to protect itself, hence the need to purchase horses.
Zhao Zhongyu did not hesitate. Although rearing private soldiers was akin to treason, and the Zhao Family's troops had long exceeded the limits prescribed by ritual laws, in such a chaotic situation, without sufficient military strength, a family could not be preserved.
So he immediately wrote two letters, one of which was an introduction letter to Liu Kun, which members of the Zhao Family could use to find Liu Kun in Bingzhou.
Furthermore, Zhao Zhongyu exchanged information with Zhao Ming. Now, with the Xiongnu advancing south and people's lives difficult, even noble families like theirs could hardly remain unaffected. Zhao Zhongyu hoped they would hoard grains, gold, silver, and cloth, so they could easily leave if something happened.
