How long does Shentong Express take from Guangzhou to Harbin?

Normal, this is quite fast. After all, it's more than 3000 kilometers. I come from Harbin. Generally, the goods sent to Guangzhou can be cleaned in three days. If it is scanned in Guangzhou in the morning, it can be delivered on the same day. If it is scanned in Guangzhou at night, it will be delivered on the fourth day.
