[Interpreted] Regarding the change on the operating expenses, first of all, sales and marketing expense, excluding SBC, mainly includes the staff salaries and other related expense, channel promotion costs, sponsorship fees for our eSports team as well as expenses for the online and offline events.
In the third quarter this year, the sales and marketing expense, excluding SBC, increased on a sequential basis, mainly due to our increased marketing efforts for the eSports tournament resulting from the increase in the eSports tournament frequency as compared to the prior quarter.
It was also due to our increased investments into those eSports teams which is known for marketing. We are quite positive about the long-term development of the eSports industry, and we will continue to invest in eSports-related events and eSports team sponsorship going forward. Meanwhile, we will also consistently upgrade our product features to improve our user conversion, and we will also enhance our content. In the future, we expect the absolute value of our sales and marketing spend to increase, as well as a percentage of total revenue to continue to improve.
Speaking of G&A, for the third quarter of 2020, G&A, excluding SBC, increased on a sequential basis, mainly due to higher professional service fees resulting from the merger. And going forward, we believe the G&A spend will grow at a slow and steady rate. With higher operating leverage, we expect the G&A spend as a percentage of the revenue to further decrease.
And lastly, on the R&D cost. In the third quarter, R&D, excluding SBC, increased quarter-over-quarter, mainly because the increase in expenditures for the research and the development of new products to maintain the leading position of our technology and products in the industry as well as the increased headcount for the overseas R&D personnel. And the staff salaries accounted for more than 80% of our total R&D expense.
So going forward, although we will continue to invest in our R&D development now to maintain our industry leadership, we think our overall R&D spend will grow steadily. And with the rapid revenue growth, we expect our R&D cost as a percentage of revenue to further improve.
