At least for now
The telegram should be sent to the post office
You can go to the China Post trade office for consultation

4. Label telegram: The maximum processing time is the same as for ordinary telegrams.
5. Telegramof floral etiquette:
Ordinary affairs: According to the deadlines stipulated by the telecommunications department, telegrams submitted by the sender before 11 a.m. (including 11 a.m.) will be delivered on the same day and telegrams submitted after 11 a.m. The telegram was delivered before noon the next day.
Scheduled Delivery Service: This is a service that is delivered according to the date and time specified by the shipper. For floral telegrams to be delivered, the sender must deliver them at least 24 hours in advance: the specified time. the delivery time is limited to 08:00-21:00, the difference between the delivery time and the delivery time specified by the user is half an hour before or after. During peak periods such as Spring Festival, New Year, Christmas and Valentine's Day, only delivery services will be provided on designated dates, and delivery services at designated times will not be provided.s provided.
Of course, it is still used
From discovery to human use, great scientific achievement often requires the continued efforts of several generations. Maxwell predicted the existence of electromagnetic waves, but failed to confirm his prediction through personal experiments; Hertz first confirmed the existence of electromagnetic waves through flashing water, but categorically denied the possibility of using electromagnetic waves for communication. He believed that to use electromagnetic waves for communication, you would need a giant reflector the size of the European continent. However, the lightning of “air waves” illuminated the immortal journey of two young people. These two young people were called Popov and Marconi.
——On May 7, 1895, Popov, who was only 36 years old, read aloud "The relationship between metal filings and electric oscillation"at the physics branch of the Russian Physical and Chemical Society in St. Petersburg. . paper and gave a public demonstration of the radio receiver he invented. When his assistant Rybkin turned on the spark generator at the other end of the corridor, Popov's radio receiver rang when he turned off the generator, the ringing immediately stopped; Decades later, to commemorate Popov's historic initiative on that day, the Soviet government of the time designated May 7 as "Day of the Invention of Radio." On March 24, 1896, Popov and Rybkin used their self-made radio transceiver at the annual meeting of the Russian Physical and Chemical Society., performed a performance of transmitting Morse code by radio. The message sent at that time was “Heinrich Hertz” to express respect for this pioneer of electromagnetic waves. Although the communication distance at the time was only qWith a length of 250 meters, it was the first telegram with clear content transmitted by radio in the world.
——In June of the same year, the 21-year-old Italian Marconi also invented the wireless telegraph receiver and obtained a patent in the United Kingdom. At that time, the communication distance was only 30 meters.
——Marconi was born on April 25, 1874 in Bologna, Italy. He has had a wide range of hobbies since he was a child and is very interested in electricity, mechanics and chemistry. At the age of 13, inspired by Hertz's paper confirming the existence of electromagnetic waves, he had the bold idea of using electromagnetic waves to communicate. He experiments with radio communications sometimes in his attic, sometimes in his yard or on his farm. In 1894, he successfully transmitted and received radio communications over a distance of 2 miles.
——The path to Marconi's invention was strewn with thorns. After theWhen his application for government funding failed, he decided to go to England in 1896. There, he received the attention and support of scientific and industrial circles and obtained a patent. In 1897, Marconi founded the world's first radio equipment company, the American Marconi Company. On May 18 of the same year, Marconi successfully conducted radio communications across the Bristol Channel. In 1898, the British organized a yacht race which ended at sea 20 miles from the coast. The "Dublin Express" specially hired Marconi to announce the news by radio. As soon as the yacht reached the end, it used radio waves to immediately inform the people on the shore of the victory result, and the audience was overjoyed. It can be said that this was the first practical application of radio communications.
——The invention of the diode played a positive role in promoting Marconi's research. In 1901, he succeeded in leading communlong distance radio communications across the Atlantic. The experiment was carried out between the United Kingdom and the island of Finland, 2,700 kilometers apart. Since then, humanity has entered a new era of long-distance communication using radio waves.
——On July 20, 1937, Marconi died of illness in Rome. Tens of thousands held a state funeral for him in Rome; the British Post Office's telegraph and wireless telephone services were interrupted for 2 minutes to express respect for this pioneer who was the first to apply radio theory to communications and won the Nobel Prize in Physics in 1909. respect and condolences.
