So what now happens in Haryana is, all principals and teachers are divided into hundreds of WhatsApp groups and anytime something needs to be communicated, it's just posted across all WhatsApp groups.
现在在 Haryana 省我们是这么做的， 我们建立了几百个 WhatsApp 群， 把所有的校长和老师都加到里面， 这样当我们需要传达一些信息的时候， 我们就直接通过WhatsApp群发就行了。
