Revenue from our Taiwan segment increased by $1.7 million from $30.3 million for the three months ended September 30, 2021 to $32.0 million for the three months ended September 30, 2022. The revenue in local currency was increased due to the performance and operation bonus resulting from the sales of insurance products increase from Uniwill and Law Broker but partially offset by the foreign exchange fluctuation from the substantial depreciation of the New Taiwan Dollar against the U.S. dollar.
Revenue from our PRC segment decreased by $0.6 million from $1.3 million for the three months ended September 30, 2021 to $0.7 million for the three months ended September 30, 2022. The overall insurance industry environment was declining during 2022 in PRC and customers in PRC were less willing to buy those insurance products in 2022, which resulted in the decrease of revenue in the PRC segment.
Revenue from the Hong Kong Segment was primarily derived from reinsurance commission on sales of insurance products from other insurers to Taiwan Life Insurance Co., Ltd. (“Taiwan Life”) for risk management. Revenue decrease from our Hong Kong segment for the three months ended September 30, 2022 continued compared to that of the three months ended September 30, 2021 due to the termination of certain of our reinsurance agreements and the discontinuation of travel insurance.
Cost of revenue and gross profit
The cost of revenue mainly consists of commissions paid to our sales professionals. The cost of revenue increased by $2.9 million from $17.1 million for the three months ended September 30, 2021 to $20.0 million for the three months ended September 30, 2022. The increase in the cost of revenue was mainly resulted from the revenue increase of both Uniwill and Law Broker. In addition, the bonuses paid to agents also increased due to the outstanding sales performance from senior agents with higher commission rates.
Consequently, the gross profit margin decreased from 46.0% for the three months ended September 30, 2021 to 38.7% for the three months ended September 30, 2022.
Selling expenses
Selling expenses were mainly incurred by Law Broker and Uniwill in connection with costs related to marketing and advertising. For the three months ended September 30, 2022, selling expenses were $0.9 million, reflecting an increase of $0.5 million, compared with $0.4 million of selling expenses for the three months ended September 30, 2021. The increase in the selling expenses was caused by the marketing activities during the three months ended September 30, 2022. For the same period in 2021, the adverse impact from the outbreak of COVID-19 in Taiwan had substantially restricted our marketing activities in Taiwan, leading to less selling expenses in such period.
General and administrative expenses
General and administrative (“G&A”) expenses are principally comprised of salaries and benefits for our administrative staff, office rental expenses, travel expenses, depreciation and amortization, entertainment expenses, and professional service fees. For the three months ended September 30, 2022, G&A expenses were $6.4 million, reflecting a decrease of $0.8 million, compared with $7.2 million of G&A expenses for the three months ended September 30, 2021. The decrease in the general and administrative expenses was attributed to the recognition of compensation costs for the issuance of shares of common stock during the three months ended September 30, 2021.

For the three months ended September 30, 2022, other operating income were $3.3 million generated from the disposal of nonfinancial assets in one of the subsidiaries, Jiangsu Law.
Other income (expenses), net
Other income mainly consisted of interest income, interest expenses, gain or loss on valuation of financial assets and foreign currency exchange gain or loss. Other income were $1.4 million, reflecting an increase of $1.1 million, compared with the other income of $0.3 million for the three months ended September 30, 2021. The increase in other income was mainly due to the foreign currency exchange gain recognized from foreign currency time deposits assets and intercompany receivable and payable because of the substantial depreciation of the New Taiwan Dollar against the U.S. dollar and Chinese Yuan during the third quarter of 2022.
