Loans Payable (Textual) |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Description of remaining loan balance |  |  |  |  |  |  | The process of transferring all the equity shares of his wholly owned company, Xi'an Hanneng, to HYREF as repayment for the loan; Xi'an Hanneng is a holding company and was supposed to own 47,150,000 shares of Xi'an Huaxin New Energy Co., Ltd. ("Huaxin"), so that HYREF will indirectly receive and own such shares of Xi'an Huaxin as the repayment for the loan of Zhonghong. As of September 30, 2019, Xi'an Hanneng already owns 29,948,000 shares of Huaxin, and is in the process of obtaining the remaining 17,202,000 shares; however, Huaxin stock is halted trading by NEEQ until its 2018 annual report is filed. As of the date of this report, the partners of HYREF and the Company orally agreed to extend the due date of the equity share transfer of Xi'an Hanneng for another few months until December 31, 2019, when Xi'an Hanneng obtains the remaining 17,202,000 shares of Huaxin. Since the debt settlement agreement is not fully implemented, the loan was deemed unpaid at September 30, 2019. |  |  |  |  |  |  |  |  |  |  |
