General and administrative fees

The following table sets forth
a summary of our general and administrative expenses for the years ended December 31, 2024, and 2023. The decrease in general and administrative
fees was primarily attributable to the streamlining of our operations to focus on preparation for the Merger, which has since been abandoned.

Legal and professional fees

For the years ended December
31, 2024, and 2023, the legal and professional fees were $803,285 and $2,538,161, respectively. The decrease in legal and professional
fees was primarily attributed to the lack of non-routine activities that were present in the same period last year, such as the implementation
of reverse stock split, and amendments to the memorandum and articles of association. The absence of such non-routine exercises in the
current period has resulted in a decrease in legal and professional fees.

Other operating expenses

For the years ended December 31, 2024, and 2023, the other operating expenses
was $272,609 and $1,067,690, respectively. The decrease in other operating expenses was primarily due to the decrease in impairment loss
of long-lived assets since the majority of long-lived assets were impaired in prior year and no such large impairment in current year.
