TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.在奶奶屋子外间，一家人都挤在矮榻上坐着。"You don't look, afraid of missing any important information; You see, most of them are negative emotions."
