At 4 PM on 15/7, Sam, the nickname for Nguyen Phuoc Quy K, rode his bicycle from his mother's shop on Dien Hong street, Gia Dinh ward, to deliver eggs to customers. As he cycled, the boy recited his sales pitch: "May heaven bring favorable rain and wind, so Sam can sell eggs, and every household comes to buy."

The boy's rhyming calls make many passersby turn their heads and stop to buy. Whenever a customer places an order, Sam records it, sends the information to the shop for his mother to prepare, then picks up the goods for delivery.

Sam has maintained this work for over a year to help his family. A video capturing him cycling and reciting poetic sales calls has garnered over four million views and thousands of comments on TikTok social media. Most comments express delight at his calls, which are adapted from poetry and folk songs.

Ms. Ngoc Trang, 35, Sam's mother, said she opened the egg shop in early 2025. Last summer, road construction in front of the shop caused dust, reducing customer numbers. Sam decided to cycle and sell eggs in an area about 2 kilometers from home to find more customers.

Each day, Sam devises a new sales call, prioritizing a four-word poetic form or luc bat verse. Ms. Trang also consults folk songs and proverbs to help her son refine the content or adjust it according to the shop's promotions. Sometimes, the boy even adapts lyrics from familiar songs into sales calls and records them to play through a speaker while cycling.

When the shop first opened, it sold about 20 boiled eggs daily. After Sam started selling with poetry, sales increased to about 50 eggs. Since late last year, when Sam's video appeared online, customer numbers significantly increased as many sought to buy after watching the video.

Sam also suggested his mother distribute flyers, believing that even if passersby do not read them entirely, they would still glance for a few seconds and become aware of the shop. Interacting with customers daily, he remembers the number of people in many familiar families and knows how many eggs each household usually buys, allowing him to proactively suggest suitable promotional packages. For example, if a customer buys 10 eggs, Sam will advise them to buy 15 for a better price or to receive an additional gift.

"I'm happy because I can help mom sell more eggs," Sam said.

Ms. Trang said Sam loves his mother dearly. Seeing his mother often stay up late sorting eggs, every afternoon after school, he helps wash Vietnamese coriander and pack goods. On busy days, Sam continues to deliver orders or arrange eggs at the shop.

His mother affirmed that she does not aim to sell more goods solely through her son's efforts. Allowing her son to help sell is a way to teach him skills. Sam is instructed on how to dismount his bike, use both hands to hand over goods, and bow his head to thank customers. For each delivery, he receives 5,000 dong to manage his own spending.

"I hope my son learns to appreciate hard work, live politely, and share with his family," Ms. Trang said.
