Hi, Jessica. Nice writing and interesting journey. With the title we would write this with initial capital letters. I have just suggested a few amendments. Please remember the word 'I' should always be in capitals. In the past tense you need to say 'had a wonderful time'. (Present tense would be 'we are having a wonderful time' and future tense is 'we will have a wonderful time'). Also, after each full stop (.) you need to start the next sentence with a capital letter.  I also like Qingdao beer ...haha
