i was refused a uk visit visa one month ago

Like I said above,I was refused a uk visit visa .I stated that I want to travel to the uk on anual leave for 2 weeks, and they redused it because I stated that I do not have any relation in uk and no strong ties in nigeria. Pls I work with a travel agency company as an assistant manager with a salary of 250 thousand naira,I presented copy of a landed property. Still was refused. Now I want to re apply,and I was adviced to get an appeal letter from an immigration lawyer and attach it with my refusal letter as part of my documents while reapplying. Pls what do I do. Should I still say am travelling for my anual leave? Help me pls. Am from nigeria
