Double-entry visa

I'm an Indian citizen residing in India. I'm going on a North Korea tour from April 27th, 2020 to May 7th, 2020. I'll arrive in Beijing from India on April 25th and take a flight to Pyongyong on April 27th. On 7th May, I'll take a train from Pyongyong and arrive into Beijing on 8th May. I'll take the flight back to India on 11th May. So, I'll be in China from 25th April to 27th April and from 8th May to 11th May. I will need a doublr-entry visa. What kind of Visa should I apply for?
