I feel this height and weight is only 80, which is a little thin. Although it looks a little petite, you should strengthen your exercise if you are thin. If you are a little fatter, it may be better to be a little fatter and look healthier. If you are thin, your constitution will be weaker and your resistance will decline. So you should strengthen your exercise, build up your physique, strengthen your resistance, be healthier and more beautiful.
