then one person thought out an idea to solve this problem. he was rolland hill, a schoolmaster in england. he was the first to put forward a proposal to use stamps in 1850s. he thought it would be much more convenient for people. they could go to a nearby post office to buy stamps and put them on the envelopes before they sent letters. the post office could simply put seals on the stamps to prevent them from being used again. that was a good idea and it was accepted by tile government finally.
