简介：Zhang is very experienced in hiccups. He often hiccups because he swallows food too quickly. He has become a good doctor after a long illness. He asked Huang Yinyu to take a deep breath first, and then hold it in as quickly as possible, holding it in for as long as possible. Make it a little longer, then exhale again, repeat it several times. If it still doesn't work, there is another way.
