I'm not sure what "足忧" means. If you mean foot fungus (tinea pedis), here's how to treat it.
For mild cases, over - the - counter antifungal creams or sprays can be effective. Apply the cream to the affected area of the feet as directed, usually once or twice a day. The active ingredients such as terbinafine can kill the fungus.
Keep your feet clean and dry. Wash your feet daily with soap and water and make sure to dry them thoroughly, especially between the toes. Wear breathable shoes and change your socks often.
If the fungal infection is severe or doesn't respond to over - the - counter treatments, it's advisable to see a doctor. The doctor may prescribe stronger antifungal medications, which might be in the form of oral tablets to completely eliminate the fungus from the body.
