Jules Bianchi says he has been encouraged by Marussia's improvements despite his difficult start to the 2014 season.
Bianchi was unclassified in Australia while in Malaysia he received penalty points after colliding with Pastor Maldonado.
In Bahrain, the French driver was handed a couple more penalty points after stewards deemed he was the guilty party when he made contact with the Sauber of Adrian Sutil.
But Bianchi says he is lifted by Marussia's progress compared to last season.
"I am hoping all my bad luck is behind me now and that China will mark a turning point for a better rest of the season," he said.
"If we look at the positives, there have been good signs that we have been able to raise our performance level and have a few interesting battles in the races; I hope we can enjoy a few more in Shanghai this weekend.
"The test ran smoothly in Bahrain last week and I think this will help us with our preparations this week as we are finding out lots of new things about the package and getting strong all the time. I like the track and I am looking forward to the final long haul race before we get back to Europe."
Team principal John Booth is also hopeful that Marussia can make small gains in China this weekend.
"Although we are focusing our development efforts on the start of the European season, we hope that the progress we made at the recent test will provide us with the momentum to keep us moving forward this weekend in China, where we hope for more strong progress for Max and a little more luck for Jules," he said.
