Chinese may use form acronyms with numbers when communicating in the computer networks. Two of the most famous ones, especially when talking about Love or Romance, are 520 and 521. Borrowing the similarities when pronouncing these numbers in Putonghua, 520 means "我愛你" (I love you) and 521 means "我願意" (I do) in the net world. Hence, there are many people getting married or making marriage proposals on May20 or May21. I personally have three friends getting married on these days. Congratulations!!! May the Love and Happiness be with You, forever and ever.
Going back to these two cans of Coca-Cola from Mainland China... which is really my favourite amongst all my collections from Mainland China. The major graphics is the word "愛". However, in contemporary simplified Chinese characters, the "心" (heart) was taken away. Hence, the simplified character turned to be "爱" without the heart. Here on the cans, the heart is replaced by the words "Coca-Cola". You may simply imagine that Coca-Cola is the heart and it makes the word "Love" complete. The six words underneath "如果爱，请深爱" means "If you love, do love deeply." #cocacola #coke #cocacolachina #cocacolazero #cokezero #330mlcan #love #lovacan #cocacolalove #可口可樂
