How much blood do you need to donate to the blood donation honor card?

Take Jiangsu Province as an example, you can get an honor card by donating 4000 ml of blood.

According to the inquiry of Changshu Municipal People's Government, if you donate 4000 ml of blood in Jiangsu Province, you can get the Jiangsu Free Blood Donation Certificate (commonly known as the "Three Exemptions Certificate"). With this card, you can visit parks, tourist attractions and other government-sponsored places for free; Visiting medical institutions organized by the government is free of general outpatient fees; Free use of public transport in the city. The "three-free card" declaration was made by the blood bank that donated blood for the last time. I don't need to declare it. Under normal circumstances, wait for about 3 months, and get the card at the designated place according to the SMS notification of the blood station or the information published by the official WeChat account "Changshu Blood Donation".
