What changes have been made in the terms of tax increase and exemption in Sino-US and Sino-Japanese treaties?

In addition to the changes in the provisions on tax increase and exemption in the Sino-US Treaty and the Sino-Japanese Treaty, the following main contents have been added: both treaties provide for mutual protection of copyright; Sino-US treaties provide for mutual protection of patents; Fengtian (now Shenyang, Liaoning Province) and Anton (now Dandong, Liaoning Province) were "opened to trade by China". The Sino-Japanese Treaty stipulates unified measurement, China; Open Changsha as a trading port; "If all the troops stationed in Zhili Province (now Hebei Province) and all the troops stationed in the [protective] and [embassy] museums retreat, China will immediately open a commercial market in Beijing"; Fengtian and Dadonggou are "China's own trading ports", and China allows all Japanese ships, big or small, to engage in port trade in China. Japan attaches great importance to this article, thus breaking the restriction that only foreign ships "not at sea" can sail in the inner port of China.
