A nine-year-old boy in southern China is on a mission. He wants to turn bugs from creepy crawlies to the interesting and important creatures that they are.
While many people in urban China are scared of insects, the primary-school boy, named Zhang Heyi, understands that they support the health of our ecosystem.
Heyi is using social media to spread the word that insects are not to be feared.
"Now, many people are scared of worms, but real worms are not scary," he says.
In a video, Heyi rests his head on a table, staring at a praying mantis as it climbs onto his forehead. The boy smiles. Next, he picks up a few cockroaches that have managed to escape their holding pen.
Heyi won a "Walking Encyclopaedia" award at school for his knowledge of insects. He likes to interact with his schoolmates by talking about bugs.
"My classmates come to me if they discover bugs at school, and I also try to share my findings with them," he says.
"How does a cockroach hunt?" a teacher asks Heyi in front of her pupils. "With its front legs," Heyi says.
"How big is the biggest stag beetle?" a schoolmate asks. "Over 8cm. Oh wait, probably closer to 9cm," Heyi replies.
Heyi has 10 million fans on Douyin, under the name "The insect work of Qiqi". His latest story, posted in August, has received 236,000 views and 72,000 comments.
Heyi has learned about insects by reading books and going on night expeditions. He usually goes out with children his age, along with some adults with torches.
They stop to watch the insects and often see lots of them, such as dragonflies, mantises, ants and moths.
Heyi dreams of studying at an agricultural university when he grows up.
Five things to know about
1. Insects' bodies have three parts: the thorax, abdomen and head. Insects have two antennae and three pairs of legs. Insects are cold-blooded. Most of them hatch from eggs.
2. There are thought to be about eight million species of insects! We have not yet discovered them all.
3. The amazing insects of the gerridae family (also called water striders) are able to walk on the surface of water. They can do this by having long, thin legs which spread their weight over a wide surface area.
4. Some insects, like bees, termites and ants, live in large social communities which are well organised.
5. Cicadas are some of the noisiest insects. Some cicadas can make sounds nearly 120 decibels loud!
