Which is the slowest express delivery company?

I used to think that postal express was the slowest. It always seemed like it would take ten days and a half to arrive. But now, this is no longer the case. Nowadays, the slowest express delivery is still Tiantian Express.

Our school is in Heilongjiang, and mailing things here is already very slow. Just fine. If I buy food at Tmall Supermarket and it is shipped from the warehouse in Heilongjiang, it will take me three days to get there. But in places like Zhejiang and Chengdu, if I buy it in the morning, it can arrive in the afternoon. This has happened to me several times when I bought things for my classmates, and I was so envious.

And the postal service has now speeded up, and it is fast and relatively cheap. There is a post office in our school, and every year those graduates who choose to mail things do so here. Basically, it usually takes two days to arrive in the province. The last time I mailed the clothes back to Sichuan, it took five days to arrive. Usually when I buy things online, it takes five days for the goods shipped from Zhejiang to reach the school.

But Tiantian Express is really slow. Every time I see Tiantian Express being shipped, I have no hope in my heart and just wait for it to be mailed slowly. It should be able to arrive at our school within a week. If it's slower, it's really slow, and it won't even arrive in ten days.

Two days ago, I bought a bunch of spicy strips with my friends. At that time, just because I wanted to eat them, I bought a lot of them online, but I didn’t expect that the spicy strips that we were obsessed with would be alive for twelve days. When I got it, I no longer had any desire to eat it. Now there are still a lot of spicy strips sitting in the dormitory with no one eating them. This express delivery is beyond the century.

Books are usually sent by express delivery every day, which is also very slow, as slow as it is. Other express delivery services are similar, and many express delivery services are now trying to catch up with SF Express, and their speeds have also improved significantly.
