I also like adding shredded dried mushrooms to my fried rice and springrolls. Buying dried mushrooms is tricky, buy those that smell good. Packaged ones are better than non-packaged ones since they smell bad because of the rain and mould. Soak the mushrooms until they're soft, then shred them and fry them first with oil. Fry the other ingredients first, then the rice. Then fry them together.
Traditional spring rolls use green bean sprouts, shredded carrots and dried mushrooms and shredded pork, and another Chinese vegetable which looks like spring onion but is yellow and light green called 韮王 gau wong. You have to boil or fry the pork and veg before wrapping them.
I've made spring rolls with chicken shreds and mango before, they taste good but the spring rolls will turn soft soon because of the water inside.
You can also add peeled shrimps or dried shrimps to your fried rice, and peeled shrimps to your springrolls, together with mixed fruit cocktail and mayonnaise, which you may find in every restaurant.
