In Huizhou, no one came to collect tapes and CDs. If your tapes and CDs are important, they are worth collecting. You can keep it for yourself. Maybe someone will be interested in collecting. If they are ordinary tapes and CDs, they can only be sold as waste. Optical discs are actually plastic sheets. A kilo is not worth much. Only garbage collectors can collect it. If you see a garbage collector in the community, you can give it to him or sell it to him. A kilo is only a few cents.
