Buying tetra-, hexa-, and dihydroxypyrimidine is what the world needs
, and the business has something to do. I want to buy tetra-, hexa-, and dihydroxypyrimidine, and I want to carry out it in the market and visit the merchants of various medicine shops.

At the beginning, to the first place, I asked the shopkeeper, "Do you have tetra-, hexa-, and dihydroxypyrimidine in your place?" The shopkeeper pondered with his eyebrows, and said, "I have never heard of this medicine, I am afraid that I will not have it." My heart was slightly depressed, but I did not give up, and went to another place.

I went to a store again, and saw a list of medicines on the shelf, with a wide variety of categories I asked the shopkeeper, who smiled and said, "This medicine is rare, and my shop is not prepared, so you may go to the big city to ask for it."

I didn't stop working hard, and went to the big city. In the big city, people come and go, and shops are lined up. I visited several houses, but they all said that there was no such medicine. When I was worried, I met an elderly man, who saw that I was anxious, and asked me what I was doing. I bought tetra- or six-hydroxypyrimidine to inform him. The elder said, "Although this medicine is rare, there is one in the west of the city, which specializes in strange medicines, or there is one that you ask for."

I was overjoyed when I heard it, and went to the west city. If you see it all, the facade is not big, but the fragrance of the medicine is in the room. Entering, you see a card on the cabinet, and the book "specializes in selling strange medicines". I urgently asked the shopkeeper: "Do you have tetrahydroxy-6-dihydroxypyrimidine?" The shopkeeper nodded and said: "If you have this thing, how much do you need?" I said: "Buy it." Then he paid the money to get the medicine, and returned with joy.

The way a husband seeks things is more expensive than never giving up. Although he has gone through hardships, he will eventually get something, which is also the happiness of life.
