It is reported in the news these days that Comrade Hua Ding, an expert in explosive ordnance disposal in Siping City, Jilin Province, risked his life to transfer a bomb dug from the construction site to a safe place and successfully detonated it. The key is that the bomb has been smoking in the construction site and may explode at any time. The provincial government awarded the first class merit. This shows how difficult it is to get the first class merit.
