Please help me to fix my bread to be more soft and smaller hole
The bakery is probably selling bread produced using the Chorleywood process, which is a high-volume, high-speed process that uses low-protein flours and additional ingredients (emulsifiers, gums, enrichment) to produce bread that is very light and easy to slice compared to home-baked bread. It's challenging to replicate in a home kitchen, and there's good reasons not to try as home baked bread tends to taste better and may be better for you. 

If you are getting really dense bread:


you may be over-kneading. You said you kneaded for 60 minutes, which is far too long. I rarely ever knead more than 10 minutes. Over-kneaded bread has too much gluten developed, and will be tough
it may be too dry. Much of the air in bread comes from water turning to steam, dry dough will end up with a close texture. Try adding more water and kneading with oil instead of flour
It may be under-proofed. The yeast may be retarded by too much salt, not enough heat, or being too old. It may also be you just didn't leave it long enough. If you want a light and fluffy loaf let the first rise go until  trippled
You may have knocked the dough back too much after the first rise. Many people beat the heck out of their bread after first rise, but this will undo much of the work the first rise did in creating air. Handle the dough gently when shaping and moving it into the baking pan, or you may end up losing your air
