The IRS has 800,000 property. Can we not go to the public resource platform?

You can't. According to the provisions of the Procurement Law of People's Republic of China (PRC), if the purchase amount of property in State Taxation Administration of The People's Republic of China reaches more than 800,000 yuan, it should be purchased through public resource trading platform by public bidding or competitive negotiation. Therefore, buying more than 800,000 properties of the IRS requires going to the public resource platform.
