VOV.VN – As extreme heat continues to grip Vietnam, many people are stopping by roadside drink stalls in search of relief after long hours working outdoors. Some reach for a bottle of Zero Degree Green Tea to cool down. Others choose Dr Thanh Herbal Tea or Number 1 Energy Drink before heading back to work.
But over the past month, a new habit has emerged.
Rather than immediately throwing away their empty bottles, many consumers now hold onto them for a few extra seconds. They peel back the outer label, enter a code on their phones, and wait for a result that appears almost instantly.
“Peeling a Label After Quenching Your Thirst”: A Small Habit Becoming a Summer Trend
Approaching noon, as scorching heat blankets the streets of Ho Chi Minh City, it is easy to spot people pulling into convenience stores, neighborhood shops, and roadside beverage stands to grab a cold drink.
Some stand beneath the shade of a tree, sipping Dr Thanh Herbal Tea to relieve their thirst and help cool their bodies amid the relentless heat.
Others remain seated on their motorbikes, taking a brief break between deliveries or rides while enjoying the bold taste of a bottle of Number 1 Energy Drink to recharge before returning to work.
Many people who drink Dr Thanh Herbal Tea, Green Tea Không Độ, or Number 1 Energy Drink are no longer throwing away their bottles immediately. Instead, they spend a few extra seconds peeling the label and entering a promotional code to try their luck.
Elsewhere, groups of young friends gather at small roadside cafés during lunch breaks, each holding an ice-cold bottle of Green Tea Không Độ to cool off, ease stress, and take a break from the pressures of work and study.
At first glance, everything seems perfectly ordinary.
That is, until people begin noticing the promotional message printed directly on the bottle labels.
Some see friends entering codes and decide to follow suit. Others become curious after spotting the phrase “Peel and Win Instantly” on the packaging and choose to hold onto the bottle a little longer instead of discarding it right away.
A quick pull along the perforated edge reveals a small string of characters beneath the label. Phones come out on the spot. The code is entered according to the instructions, and within seconds, the result appears on the screen.
Participating is simple: peel the label, retrieve the code, and either send it to hotline 6020 or enter it at https://xengaytrunglien.com to receive an instant result.
“I Had Just Entered the Code and It Already Said I Won”: The Excitement That Has People Trying It on the Spot
Early one afternoon, Quân, a ride-hailing driver working in the Hiệp Bình area of Ho Chi Minh City, parked beneath a tree near a university while waiting for his next passenger.
He was still holding the empty bottle of Number 1 Energy Drink he had just finished.
While chatting with another driver taking a break nearby, he was asked whether he had tried the “peel the label and enter the code” promotion.
“I thought it was just advertising. I had no idea you could enter a code and get the result immediately,” Quân recalled.
Following his colleague’s instructions, he peeled back the label along the designated tear line and entered the code into his phone.
Just seconds later, the system informed him that he had won a VND 50,000 mobile-phone top-up card.
After peeling back the label along the perforated line, participants can enter their code at https://xengaytrunglien.com or send it via SMS to hotline 6020 to receive an immediate result on their phones.
The enthusiasm is not limited to ride-hailing drivers like Quân. Similar scenes are increasingly common at roadside beverage stalls during the hottest days of summer.
At a drink stand on Đinh Thị Thi Street in the Vạn Phúc urban area of Ho Chi Minh City, shop owner Quỳnh said she has recently noticed many customers purchasing Green Tea Không Độ, Number 1 Energy Drink, or Dr Thanh Herbal Tea and then remaining at the shop to enter promotional codes.
“At first, I didn’t pay much attention,” Quỳnh said. “Then I noticed customers holding onto their bottles after buying them. Some were entering codes, while others were showing off phone-credit prizes they had just won. That’s when I realized there was a label-peeling promotion.”
According to Quỳnh, there have been afternoons when several customers won mobile-phone top-up cards in the span of a single lunch period, prompting other patrons nearby to try it as well.
At many roadside beverage stalls, drinking a bottle and immediately entering a promotional code has become an increasingly familiar sight this summer.
No App Downloads, No Registration Required: Simplicity Drives Participation
What makes the campaign memorable is not a complicated process. Quite the opposite.
Participation is so straightforward that almost anyone can try it on their very first attempt.
Consumers simply peel the label from a bottle of Dr Thanh Herbal Tea, Green Tea Không Độ, or Number 1 Energy Drink, retrieve the code hidden underneath, and enter it at https://xengaytrunglien.com or send it via SMS to hotline 6020.
Within seconds, the result appears directly on their phone. The entire process takes less than a minute. No app download is required. No account needs to be created. No lengthy verification steps stand in the way.
For many outdoor workers, cooling down with Dr Thanh Herbal Tea during periods of extreme heat also gives them an easy opportunity to win valuable prizes.
For many people—particularly ride-hailing drivers, factory workers, and older consumers who may not be comfortable with complex smartphone procedures—that simplicity makes participation easy and enjoyable.
And because it is so easy, the habit of “peeling the label after finishing a drink” has spread rapidly by word of mouth.
From roadside cafés and neighborhood shops to midday rest stops, it is now common to see people drinking their beverages while glancing down at their phones to enter a code and test their luck.
Double the Excitement: Instant Wins and a Chance at VND 100 Million
According to the promotion, more than 500,000 mobile-phone top-up prizes are being distributed throughout the summer campaign, which runs from April 20 through August 31.
On average, someone somewhere in Vietnam wins a prize every few minutes.
To date, more than 60,000 prizes have already been claimed, while hundreds of thousands of rewards remain available nationwide.
As a result, the sight of people peeling labels and entering codes immediately after finishing a drink is no longer uncommon at roadside beverage stalls or rest stops during the hottest hours of the day.
The excitement doubles this summer, as consumers not only have the chance to instantly win from more than 500,000 mobile-phone top-up prizes, but also to compete for a Special Prize worth VND 100 million in cash when purchasing Dr Thanh Herbal Tea, Green Tea Không Độ, or Number 1 Energy Drink.
Daily prizes are awarded through an instant-win mechanism, with rewards automatically credited within 24 hours after confirmation.
In addition, participants are entered into drawings for three Grand Prizes worth VND 100 million each and 30 First Prizes worth VND 10 million each.
The public livestream drawings are scheduled to take place at 10:00 a.m. on June 4, July 20, and September 4, and will be broadcast on the official Facebook pages of Dr Thanh Herbal Tea, Green Tea Không Độ, and Number 1 Energy Drink.
During brief pauses in the middle of a sweltering summer day—whether standing beneath a tree, sitting outside a shop, or taking a few minutes between rides—the simple act of peeling a bottle label after a refreshing drink is gradually becoming part of many people’s routine.
It takes almost no time.
There are no complicated steps.
And sometimes the result appears almost immediately.
Perhaps that is why more and more people are no longer throwing away their bottles the moment they finish their drink.
Instead, they hold onto them for just a few extra seconds and peel back the label.
Because who knows?
At that very moment, their phone might light up with a winning notification from Dr Thanh Herbal Tea, Green Tea Không Độ, or Number 1 Energy Drink.
