Yesterday I went to the Cainiao Yizhan, a package drop-off point where put all of the parcels people bought from online shopping,bought by people online are kept. I wanted to get my parcel of a set of calligraphy tools which contains a writing brush, a bottle of tusche and a stack of rice paper.

It’s a very long sentence so I broke it into two.

A reasonable excuse is that I keput my tools of calligraphy at home, but I am in school now.

After unwrapping the package I started to write kaishu, namelywhich is regular script.

You were using the past tense in your previous sentences. It's best to apply parallelism and use the same tense here, too.

Persistency is also one of the most crucial factors of habit formation.

'Persistence' sounds better than 'persistency' but you do you.
