#Why Can't Table Tennis Balls Pass Train Security# I remember when I was a child, table tennis balls would catch fire easily when damaged; they must have a low ignition point and belong to flammable solid items, so they definitely cannot be brought on a train. After all, safety comes first! In the future, if everyone wants to take sports equipment on the train, it's best to understand the relevant management regulations in advance to avoid unnecessary trouble later on! $BNB $SOL $BTC #“圣诞老人行情”再现 #灰度提交Horizen信托文件 #BinanceLabs投资Usual #币安LaunchpoolBIO
