Siheyuan: After I Learned to Understand Animals, I Went on a Rampage

[Period] + [comedy] + [one female lead] + [animals] + [pure love]

"Pigeon: Xu Damao's underwear has three holes in it! He spent the night at his mistress's place, the one with the blue qipao!"

"Old Locust Tree: He Yuzhu stuffed stinky socks into my hollow again! That's the third time this month!"

"Poison Snake Moyu: Chen Xiangyang! Keep pretending you can't hear me, and I'll spill the beans about you spying on Officer Su while she was bathing!"

By day, he delivers mail, while his left hand intercepts secret enemy messages:

★ A carp witnesses the Beihai dismemberment case, with the killer's blue workwear stuck to its scales.

★ A rat reports the grain warehouse arson. The Rat Special Forces assemble at the culprit's home.

At night, back in the courtyard, his right hand exposes the villains' schemes:

☆ Banggeng gets caught stealing a chicken after a dog rats him out, and Qin Huairu's tearful act fails for the first time.

☆ Xu Damao gets caught sneaking around with his lover late at night and is dive-bombed by a flock of pigeons, leaving his face covered in droppings.

★ Period mystery + hilarious animal antics ★ Courtyard villains vs. real beasts ★

"Xiangyang, what exactly are you carrying in that mailbag, letters or the whole courtyard's death warrants?", from the terrified Third Uncle
