What exactly are you talking about? If it's to get into Saffron City, then a person in Celadon will give you the 'tea' item and you take it to the guard in the guardhouse blocking Saffron City.
When you enter Celadon City, head to the Mansion there, the lady there will give you the 'tea', give it the guard at the gate for Saffron City, and he will share it round, allowing you access to Saffron City.
You can enter saffron city from four different areas, the route east of celadon city, the route north of vermilion city, the route west of lavendar town and the route south of cerulean city. But a guard doesn't let you enter saffron city so here's what you have to do: Go to celadon city and find the celadon mansion its a large building next to the Pokemon center and on the first floor talk to the old lady she will hand you Tea. Now take that to the guard and he will let you go to saffron city.
The guard is only guarding to saffron city. Do you go into houses? The way you get to celadon city is to go to the house on top. Follow the road until you reach the stairs. Go out the door and you should be in celadon
There is a Celadon Mansion its next to the Pokemon center on the first floor you will find an old lady near some Pokemon talk to her to receive some tea give this to the security guard blocking saffron city he will let you pass after taking the tea.
