You may be true. She looks too good on her photos. For those photos taken in sunny days, she had an intact make up and hair style in her photos which make me think she actually had a crew with her.
This is a kind of marketing. Some youtubers are also produced in this way and I am not mad at it.
Btw, for the videos,I guess the target audience are Chinese so her did not speak it English which is not a legit evidence to show if she can speak english or not.
So, who wants to put up pictures looking bad. I fix my hair and makeup and put on nice clothes for my pics and videos too. And if I was out blogging about a tourist attraction or something. I would stop and freshen up my make up and hair too. Why would somebody be filming or taking pics for a long shoot and just let the sun and wind melt their makeup and blow their hair all over their head? C'mon yall.
