Risks and Uncertainties [Abstract] |
Concentration Risk Disclosure [Text Block] | (18) Concentration of Credit Risk Financial instruments for which the Company is potentially subject to concentration of credit risk consist principally of cash. The Company places its cash in reputable financial institutions in the PRC and the United States. Although it is generally understood that the PRC central government stands behind all of the banks in China in the event of bank failure, there is no deposit insurance system in China that is similar to the protection provided by the Federal Deposit Insurance Corporation (“FDIC”) of the United States as of December 31, 2018 and December 31, 2017. On May 1, 2015, the new “Deposit Insurance Regulations” was effective in the PRC that the maximum protection would be up to RMB500,000 (US$71,672) per depositor per insured financial intuition, including both principal and interest. For the cash placed in financial institutions in the United States, the Company’s U.S. bank accounts are all fully covered by the FDIC insurance as of December 31, 2019 and 2018, while for the cash placed in financial institutions in the PRC, the balances exceeding the maximum coverage of RMB500,000 amounted to RMB38,779,345 (US$5,558,806) as of December 31, 2019.
