[3] On July 3, 2014, Digital Information entered into an equity investment agreement to acquire 49% of the equity interest of Nanjing Wei You Xue Information Technology Co., Ltd. ("Wei You Xue"), with an aggregate consideration of RMB 1,862,000 (approximately $0.30 million as of March 31, 2019). The Company uses the equity method to account for the investment, because the Company has the ability to exercise significant influence but does not have control over the investee. Wei You Xue qualified as a related party thereafter. For the continual losses of Wei You Xue, the company believes the probability of recovering the investment in Wei You Xue is low. Therefor the balance of $ 76,337 investment in Wei You Xue is fully impaired in fiscal year 2019.
