My name is Li Na, 28 years old this year and I have been engaged in the xx hotel for 3 years as a room attendant .As there was no chance of promotion,I quit the job in February this year and came to xx hotel to work as a room supervisor .Because this hotel is just a Three-star hotel, it's not the place I want to work for a long time .So I hope you can give me an opportunity to play my specialties,I will do my best to make everything well. 我能力有限,只能到这个地步了,应该问题不大。
