CCB's quick profit is the financial management of CCB's cash increase money market fund (code 000693), so the specific income depends on the current income of CCB's cash increase money fund.

If the income of 10,000 copies on that day is 0.82, then the income of buying 40,000 copies a day is 40,000 * 0.82/10000 = 3.28 yuan.
