We've done three. We're planning another one in July in the north of the country. So, we certainly still do open-heart, but you can see the contrast between everything that was shipped in -- we ship everything, instruments. We had explosions because the kit was designed and installed by people who weren't used to it.
我们已经做过三次，正准备在7月 在这个国家的北部再做一次。因此我们当然还在做开胸手术， 但你们能看出装运前后所有东西都有差别 我们什么都要运输，设备会爆炸 因为制作安装设备的人以前不是做这个的。
